memory reporting of clients argv (#7874)
track and report memory used by clients argv.
this is very usaful in case clients started sending a command and didn't
complete it. in which case the first args of the command are already
trimmed from the query buffer.

in an effort to avoid cache misses and overheads while keeping track of
these, i avoid calling sdsZmallocSize and instead use the sdslen /
bulk-len which can at least give some insight into the problem.

This memory is now added to the total clients memory usage, as well as
the client list.
