Adding a new type mask for key space notification, REDISMODULE_NOTIFY_MODULE, to enable unique notifications from commands on REDISMODULE_KEYTYPE_MODULE type keys (which is currently unsupported).
Modules can subscribe to a module key keyspace notification by RM_SubscribeToKeyspaceEvents,
and clients by notify-keyspace-events of redis.conf or via the CONFIG SET, with the characters 'd' or 'A'
(REDISMODULE_NOTIFY_MODULE type mask is part of the '**A**ll' notation for key space notifications).
Refactor: move some pubsub test infra from pubsub.tcl to util.tcl to be re-used by other tests.

Before this commit using RM_Call without "!" could cause the master
to lazy-expire a key (delete it) but without replicating to replicas.
This could cause the replica's memory usage to gradually grow and
could also cause consistency issues if the master and replica have
a clock diff.
This bug was introduced in #8617
Added a test which demonstrates that scenario.

In the initial release of Redis 6.2 setting a user to only allow pubsub access to
a specific channel, and doing ACL SAVE, resulted in an assertion when
ACL LOAD was used. This was later changed by #8723 (not yet released),
but still not properly resolved (now it errors instead of crash).
The problem is that the server that generates an ACL file, doesn't know what
would be the setting of the acl-pubsub-default config in the server that will load it.
so ACL SAVE needs to always start with resetchannels directive.
This should still be compatible with old acl files (from redis 6.0), and ones from earlier
versions of 6.2 that didn't mess with channels.
