[Core Feature] Capture and save documentation from flytekit entities

[katrogan]

Motivation: Why do you think this is important? See https://github.com/flyteorg/flyte/issues/531 for a richer discussion on this feature. For this specific issue, we will want to capture user documentation, links to source code and commit version and pipe that through the Flyte system and make entity descriptions for tasks, workflows, launch plans and executions retrievable via a separate endpoint.

Goal: What should the final outcome look like, ideally? It should be possible to add RST-formatted documentation inline with flytekit entity definitions or when launching executions from any means and have that information made retrievable by end users.

Describe alternatives you've considered Again, see https://github.com/flyteorg/flyte/issues/531
