Caching

This is a series of tickets to improve the flytekit authoring experience. If any changes are not possible to make in a backwards-compatible way, split it out into a separate ticket.

Merge options into a dataclass and rename argument

Currently there are three configurations for cache control: cache_serialize, cache_version, cache_ignore_input_vars. We should rename these to serialize (bool) , version (remains a str), and ignore (update type to list[str]|str|None=None).

This object should then be the input to the cache argument in the task decorator, which should be of type bool | Cache, and is False by default.
