[Pulp-dev] Pinning dependencies in Pulp 3

[Tatiana Tereshchenko]

+1 to pin dependencies and use dependabot

If we were to pin to Z releases, then we'd need to release pulp 3 package
with any Z release of any dependency we pin.
And in case of any [security] fix in any dependency, users would need to
wait for us to release pulp with updated dependency version.

If my logic above is correct, I'm +1 to pin to Y releases. I think most (if
not all) breaking changes we observed were in the Y releases.
