[4.6.1] Supporting setting CLIENT INFO via CLIENT SETINFO

[chayim]

This pull request cherry-picks the CLIENT SETINFO (#2857) from the 5.0 branch for 4.6. This adds support for one of the missing Redis 7.2 commands back to the 4.6.1 branch, while at the same time allowing users to disable the request if so desired.
