BLPOP when there are elements in the list works in the same way as LPOP
does. Due to this they also does the same repetitive action and logic
for the same is written at two different places. This is a bad code
practice as the one needs the context to change the BLPOP list pop code
as well when the LPOP code gets changed.
Separated the generic logic from LPOP to a function that is being used
by the BLPOP code as well.

Expose new `loading_rdb_used_mem` showing the used memory of the server
that saved the RDB file we're currently using.
This is useful in diskless replication when the total size of the rdb is
unkown, and can be used as a rought estimation of progres.
Use that new field to calculate the "user friendly"
`loading_loaded_perc` and `loading_eta_seconds`.
Expose `master_sync_total_bytes` and `master_sync_total_bytes` to complement
on the existing `master_sync_total_bytes` (which cannot be used on its own
to calculate progress).
Add "user friendly" field for `master_sync_perc`

Perform full reset of all client connection states, is if the client was
disconnected and re-connected. This affects:
* MULTI state
* Watched keys
* MONITOR mode
* Pub/Sub subscription
* ACL/Authenticated state
* Client tracking state
* Cluster read-only/asking state
* RESP version (reset to 2)
* Selected database
* CLIENT REPLY state
The response is +RESET to make it easily distinguishable from other
responses.

- rdbSaveSingleModuleAux() used RedisModuleIO's "bytes" field for
tracking written bytes before calling moduleInitIOContext() which sets
"bytes" to zero
- rdbSaveObject() re-initialized RedisModuleIO too late
This return value is not used at the moment since it's only tested
against -1, and the actual byte count isn't used yet.

This will allow to use: RedisModule_CreateStringPrintf(ctx, "%s %c %s", "string1", 0, "string2");
On large string, the previous code would incrementally retry to double the output buffer.
now it uses the the return value of snprintf and grows to the right size in one step.
and also avoids an excessive strlen in sdscat at the end.

Make it possible for redis-cli cluster import to work with source and
target that require AUTH.
Adding two different flags --cluster-from-user, --cluster-from-pass
and --cluster-askpass for source node authentication.
Also for target authentication, using existing --user and --pass flag.
Example:
./redis-cli --cluster import 127.0.0.1:7000 --cluster-from 127.0.0.1:6379 --pass 1234 --user default --cluster-from-user default --cluster-from-pass 123456
./redis-cli --cluster import 127.0.0.1:7000 --cluster-from 127.0.0.1:6379 --askpass --cluster-from-user default --cluster-from-askpass

Few config settings are also reflected by the INFO command.
these are mainly ones that are important for either an instant view of
the server status (to compare a metric to it's limit config),
Important configurations that are necessary in the crash log (which
currently doesn't print the config),
And things that are important for monitoring solutions (such as
Prometheus), which rely on INFO to collect their data.
Add cluster_connections to INFO CLUSTER:
This makes it possible to be combined together with connected_clients
and connected_slaves and be matched against maxclients

In redisFork(), we don't set child pid, so updateDictResizePolicy()
doesn't take effect, that isn't friendly for copy-on-write.

The reason that we want to get a full crash report on SIGABRT
is that the jmalloc, when detecting a corruption, calls abort().
This will cause the Redis to exist silently without any report
and without any way to analyze what happened.

The bug occurs when 'callback' re-registers itself to a point
in the future and the execution time in non-negligible:
'now' refers to time BEFORE callback was executed and is used
to calculate 'next_period'.
We must get the actual current time when calculating 'next_period'
