DX-1780: add HEXPIRE command

[CahidArda]

Adds HEXPIRE command:

# With seconds
redis.hset("myhash", "field1", "value1")
redis.hexpire("myhash", "field1", 5)

assert redis.hget("myhash", "field1") == "value1"

time.sleep(5)

assert redis.hget("myhash", "field1") is None

# With a timedelta
redis.hset("myhash", "field1", "value1")
redis.hexpire("myhash", "field1", datetime.timedelta(seconds=5))

Can you make the GitHub action pass? It seems like it is failing from formatting. I usually run these:
poetry run pytest
poetry run ruff format .
poetry run ruff check .
poetry run mypy --show-error-codes .

I fixed the formatting issue, but the tests won't pass because hexpire isn't deployed to regional dbs yet
