Wrong type annotation on fcall methods

[alethiophile]

The argument signature for the fcall methods reads:

self, function, numkeys: int, *keys_and_args: Optional[List]

Per PEP 484, the type annotation for an argument list should be the type of the expected elements, not List. This causes mypy to return spurious errors on code including the fcall method.

I believe this annotation should be *keys_and_args: Any.

Hey, thanks for reaching us out! Fix will be soon, but it will go to next major release due to API changes

Thanks for the quick fix.

Just searching through that file, I find the following other functions which may have similar problems:

command_getkeysandflags, config_get, config_set, info, blmpop, lmpop, tfcall, tfcall_async

These have the same problem, but I'm not sure if it's actually incorrect, due to them using the list_or_args helper which I'm not sure how it's used:

sdiff, sdiffstore, sinter, sinterstore, smismember, sunion, sunionstore, hmget

These have the same problem, but it may not matter as much because I assume they're internal:

_evalsha, _tfcall
