Improve signature of Repository.create_repo

[xmo-odoo]

The docstring stated that "*" and "none" were valid values for the
organization, but neither was actually supported (unless your
organization was called "none").

Remove the misleading information from the docstring, and add support
for passing in an actual Organization as that's convenient for typing and clarity.

Fixes #2116

[s-t-e-v-e-n-k]

It's a good start, I have some concerns inline.

Finally came around to writing a test, suite passes locally (at least when running tox straight).

Not sure how the replay files are supposed to get generated to I created one by hand copying the one from the regular call, and copying over the org data from the fork's owner key (as that's roughly similar, though not exactly the same payload the differences don't matter for this case) to simulate the organization fetch.

@s-t-e-v-e-n-k are there additional things you need me to change?

[xmo-odoo]

Ping, is this still of interest or should I just close it?
