The idea is add the possibility to define a cache expiration period
to avoid confusion, is seems the best solution is to consider the cache expiration based on the task definition of the reading process

API:
add a new cache_expiration parameter to flytekit.task

@task(cache=True, cache_version='v1', cache_expiration=timedelta(days=7))

will define a task that will only use the cache, if the cache is less then a week old
