Slowness feedback

[bgandon]

Reported in telia-oss#262 (comment):

@awnumar has tested with github.com/cloudfoundry-community/github-pr-resource and can confirm they see the same issue with that resource for a large repository.

• Initial get is extremely slow, hangs on Switched to a new branch 'master' and generally takes a long time to work, or more likely fail, after 20 minutes.
• put is also very slow, and they can't speed it up with skip_download because the put requires Version info that's attained from the implicit get, and they can't use depth:1 because then it fails with fatal: refusing to merge unrelated histories

See: telia-oss#262

Ah, that no good indeed.. 😞
I also am unsatisfied with how the resource behaves on my side.
The codebase needs to be equipped with a unit-test safety net, and then thoroughly reviewed/refactored.
