Allow Feast apply to import files recursively (and add .feastignore)

[tsotnet]

Signed-off-by: Tsotne Tabidze tsotne@tecton.ai

What this PR does / why we need it: We add functionality to feast apply to recursively look into the feature repo and import all files to find Feast Objects for apply. Also, we add .feastignore file where users can define which paths to ignore (similar to .gitignore). This format can understand comments (with #) and matches (* and **).

Which issue(s) this PR fixes:

Fixes #

Does this PR introduce a user-facing change?:

* `feast apply` will recursively parse files in feature repo sub directories
* `.feastignore` will allow defining paths to ignore during `feast apply`, similarly to `.gitignore`

only comment is to document this functionality, but if you want to do it in a separate diff feel free to merge

I agree. Aside from @oavdeev's comment the only thing that is missing is documentation. Would you mind adding a page under Reference in our documentation to describe the functionality of .feastignore? We should probably also mention the .feastignore in the Feature Repository section.

@woop If I understood correctly, I need to go through the documentation changes through GitBook. If so, let's merge this independently.
