#2215 [Core feature] [flytekit] Add code to be able to mock fetched Flyte entities Issue created by wild-endeavor Motivation: Why do you think this is important? Be able to mock out fetched Flyte entities in the flytekit interactive experience. After #867 is merged, users will be able to do something like this

from flytekit.remote.remote import FlyteRemote
# Constructor to FlyteRemote will be changing shortly
remote = FlyteRemote.from_config("flytesnacks", "development", config_file_path="/Users/user/.flyte/prod_basic")
fetched_task = remote.fetch_task(name="core.flyte_basics.my_task", version="v0.3.39")

@workflow
def wf(a: int) -> int:
    return fetched_task(a=a).with_overrides(node_name="my-fetched-task-node")

However,

wf

will not be locally runnable. If you try to

wf(a=5)

, you'll get an exception saying that fetched entities are not callable. However users should be able to provide a local Python function with a matching interface to mock out the fetched entity. Goal: What should the final outcome look like, ideally? Not sure... need to give this some more thought. Describe alternatives you've considered None.
