[NEW] HGETDEL support in Valkey

[Shirkulk007]

The problem/use-case that the feature addresses

There are use cases leveraging Valkey where we need to fetch specific key values within hash data type and delete them immediately after retrieval.

Description of the feature

Need a command HGETDEL which gets the key value within hash and delete it post fetching

Alternatives you've considered

Currently use 2 commands to fetch the data within hash and then delete it

Additional information

HGETDEL command is available in Redis 8.0. Need similar command in Valkey

Hey I have opened a PR for this here: #2851
The command looks like this:

127.0.0.1:6379> HGETDEL key FIELDS numfields field [field ...]

Where the response would be in order of the fields in the command and for fields not present will return a (nil).
If all the fields are deleted, it will also delete the key.
