Add support for HGETALL.WATCH command

[JyotinderSingh]

Add support for reactive queries on the existing HGETALL command by introducing HGETALL.WATCH.

This command should send push-responses to subscribed clients whenever the data inside the respective hash set changes.

As a part of this feature, you are also required to add support for the same to the dicedb-go SDK inside the watch_command.go file.

Reference

1. You may refer to Adds support for ZRANGE.WATCH #1047 to understand the changes required to support this command.
2. Implements Command Watch Manager and Adds GET.WATCH Command Support #924 provides more background on the feature's underlying implementation (but may not be directly relevant to this issue)

Testing

1. Ensure integration tests are added, you can refer to existing .WATCH integration tests.
2. Integration tests should include both resp tests and SDK tests.

Hey @arpit1912 ! I was working on it but I kinda got stuck on how to test my changes. I'm new so it took me longer than expected.
Would you mind allowing me more time to look into this issue? Thank you.
