Unified MULTI, LUA, and RM_Call with respect to blocking commands (#8025) 
Blocking command should not be used with MULTI, LUA, and RM_Call. This is because,
the caller, who executes the command in this context, expects a reply.

Today, LUA and MULTI have a special (and different) treatment to blocking commands:

LUA   - Most commands are marked with no-script flag which are checked when executing
and command from LUA, commands that are not marked (like XREAD) verify that their
blocking mode is not used inside LUA (by checking the CLIENT_LUA client flag).
MULTI - Command that is going to block, first verify that the client is not inside
multi (by checking the CLIENT_MULTI client flag). If the client is inside multi, they
return a result which is a match to the empty key with no timeout (for example blpop
inside MULTI will act as lpop)
For modules that perform RM_Call with blocking command, the returned results type is
REDISMODULE_REPLY_UNKNOWN and the caller can not really know what happened.

Disadvantages of the current state are:

No unified approach, LUA, MULTI, and RM_Call, each has a different treatment
Module can not safely execute blocking command (and get reply or error).
Though It is true that modules are not like LUA or MULTI and should be smarter not
to execute blocking commands on RM_Call, sometimes you want to execute a command base
on client input (for example if you create a module that provides a new scripting
language like javascript or python).
While modules (on modules command) can check for REDISMODULE_CTX_FLAGS_LUA or
REDISMODULE_CTX_FLAGS_MULTI to know not to block the client, there is no way to
check if the command came from another module using RM_Call. So there is no way
for a module to know not to block another module RM_Call execution.

This commit adds a way to unify the treatment for blocking clients by introducing
a new CLIENT_DENY_BLOCKING client flag. On LUA, MULTI, and RM_Call the new flag
turned on to signify that the client should not be blocked. A blocking command
verifies that the flag is turned off before blocking. If a blocking command sees
that the CLIENT_DENY_BLOCKING flag is on, it's not blocking and return results
which are matches to empty key with no timeout (as MULTI does today).

The new flag is checked on the following commands:

List blocking commands: BLPOP, BRPOP, BRPOPLPUSH, BLMOVE,
Zset blocking commands: BZPOPMIN, BZPOPMAX
Stream blocking commands: XREAD, XREADGROUP
SUBSCRIBE, PSUBSCRIBE, MONITOR
In addition, the new flag is turned on inside the AOF client, we do not want to
block the AOF client to prevent deadlocks and commands ordering issues (and there
is also an existing assert in the code that verifies it).

To keep backward compatibility on LUA, all the no-script flags on existing commands
were kept untouched. In addition, a LUA special treatment on XREAD and XREADGROUP was kept.

To keep backward compatibility on MULTI (which today allows SUBSCRIBE, and PSUBSCRIBE).
We added a special treatment on those commands to allow executing them on MULTI.

The only backward compatibility issue that this PR introduces is that now MONITOR
is not allowed inside MULTI.

Tests were added to verify blocking commands are not blocking the client on LUA, MULTI,
or RM_Call. Tests were added to verify the module can check for CLIENT_DENY_BLOCKING flag.

support NOMKSTREAM option in xadd command (#7910) 
introduces a NOMKSTREAM option for xadd command, this would be useful for some
use cases when we do not want to create new stream by default:

XADD key [MAXLEN [~|=] <count>] [NOMKSTREAM] <ID or *> [field value] [field value]

Adds new pop-push commands (LMOVE, BLMOVE) (#6929) 
Adding [B]LMOVE <src> <dst> RIGHT|LEFT RIGHT|LEFT. deprecating [B]RPOPLPUSH.

Note that when receiving a BRPOPLPUSH we'll still propagate an RPOPLPUSH,
but on BLMOVE RIGHT LEFT we'll propagate an LMOVE

improvement to existing tests
- Replace "after 1000" with "wait_for_condition" when wait for
  clients to block/unblock.
- Add a pre-existing element to target list on basic tests so
  that we can check if the new element was added to the correct
  side of the list.
- check command stats on the replica to make sure the right
  command was replicated

Stream: Inconsistency between master and replica some XREADGROUP case (#7526) 
XREADGROUP auto-creates the consumer inside the consumer group the
first time it saw it.
When XREADGROUP is being used with NOACK option, the message will not
be added into the client's PEL and XGROUP SETID would be propagated.
When the replica gets the XGROUP SETID it will only update the last delivered
id of the group, but will not create the consumer.

So, in this commit XGROUP CREATECONSUMER is being added.
Command pattern: XGROUP CREATECONSUMER <key> <group> <consumer>.

When NOACK option is being used, createconsumer command would be
propagated as well.

In case of AOFREWRITE, consumer with an empty PEL would be saved with
XGROUP CREATECONSUMER whereas consumer with pending entries would be
saved with XCLAIM

Refactor streamAppendItem() by deleting redundancy condition. (#7487) 
It will never happen that "lp != NULL && lp_bytes >= server.stream_node_max_bytes".
Assume that "lp != NULL && lp_bytes >= server.stream_node_max_bytes",
we got the following conditions:
a. lp != NULL
b. lp_bytes >= server.stream_node_max_bytes

If server.stream_node_max_bytes is 0, given condition a, condition b is always satisfied
If server.stream_node_max_bytes is not 0, given condition a and condition b, the codes just a
	few lines above set lp to NULL, a controdiction with condition a

So that condition b is recundant. We could delete it safely.

12d7479144 streamReplyWithRange: Redundant XSETIDs to replica 
propagate_last_id is declared outside of the loop but used
only from within the loop. Once it's '1' it will never go
back to '0' and will replicate XSETID even for IDs that
don't actually change the last_id.
While not a serious bug (XSETID always used group->last_id
so there's no risk), it does causes redundant traffic
between master and its replicas

4a12047c61 XADD with ID 0-0 stores an empty key 
Calling XADD with 0-0 or 0 would result in creating an
empty key and storing it in the database.
Even worse, because XADD will reply with error the action
will not be replicated, creating a master-replica
inconsistency

1833d008b3 Support streams in general module API functions 
Fixes GitHub issue #6492
Added stream support in RM_KeyType and RM_ValueLength.
Also moduleDelKeyIfEmpty was updated, even though it has
no effect now (It will be relevant when stream type direct
API will be coded - i.e. RM_StreamAdd)

f1e7df4b7c Increment delivery counter on XCLAIM unless RETRYCOUNT specified 
The XCLAIM docs state the XCLAIM increments the delivery counter for
messages. This PR makes the code match the documentation - which seems
like the desired behaviour - whilst still allowing RETRYCOUNT to be
specified manually.

My understanding of the way streamPropagateXCLAIM() works is that this
change will safely propagate to replicas since retry count is pulled
directly from the streamNACK struct.

Fixes #5194
