Adding the ":{tag}" only if --cluster is used, so that when used against
a proxy it generates traffic to all shards.

minor fix for a bug which happen on error handling code
and doesn't look like it could have caused any real harm

This commit implements ACL for Sentinel mode, main work of this PR includes:
- Update Sentinel command table in order to better support ACLs.
- Fix couple of things which currently blocks the support for ACL on sentinel mode.
- Provide "sentinel sentinel-user" and "sentinel sentinel-pass " configuration in order to let sentinel authenticate with a specific user in other sentinels.
- requirepass is kept just for compatibility with old config files

In some cases one command added a very big bulk of memory, and this
would be "resolved" by the eviction before the next command.
Seeing an unexplained mass eviction we would wish to
know the highest momentary usage too.
Tracking it in call() and beforeSleep() adds some hooks in AOF and RDB
loading.
The fix in clientsCronTrackExpansiveClients is related to #7874

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]

Reference the correct "case", case 4, in the comment explaining the need
for case 3, when the number of request items is too close to the
cardinality of the set. Case 4 is indeed the "natural approach"
referenced earlier in that sentence.

This is a compatibility issue with redis 5.0 that was introduced by ACL.
Before this commit, setting requirepass to an empty string will result
in a server that needs an empty AUTH, unlike redis 5.0 which would
accept connections without an AUTH.

If 'delta' is negative 'mem_freed' may underflow and cause
the while loop to exit prematurely (And not evicting enough
memory)
mem_freed can be negative when:
1. We use lazy free (consuming memory by appending to a list)
2. Thread doing an allocation between the two calls to zmalloc_used_memory.

If we fail or stop to rewrite aof, we need to remove temporary aof.
We also remove temporary rdb when replicas abort to receive rdb.
But currently we delete them in main thread, to avoid blocking,
we should use bg_unlink to remove them in a background thread.
Btw, we have already used this way to removed child process temporary rdb.

- Clarify some documentation comments
- Make sure blocked-on-keys client privdata is accessible
from withing the timeout callback
- Handle blocked clients in beforeSleep - In case a key
becomes "ready" outside of processCommand
See #7879#7880

This cleans up and simplifies the API by passing the command name as the
first argument. Previously the command name was specified explicitly,
but was still included in the argv.
