Cache project avatars stored in Git

Related issue: https://gitlab.com/gitlab-org/gitlab-ce/issues/14363

See merge request !3272

The avatar logic has been moved from Project to Repository as this makes
caching easier. The logic itself in turn has been changed so that the
logo file names are cached in Redis. This cache is flushed upon pushing
a commit but _only_ if:

1. The commit was pushed to the default branch
2. The commit actually changes any of the logo files

If no branch or commit is given the cache is flushed anyway, this
ensures that calling Repository#expire_cache without any arguments still
flushes the avatar cache (e.g. this is used when removing a project).

Fixes gitlab-org/gitlab-ce#14363

Adjusted behavior so canceled builds tagged as allowed to fail do not fail build

## Are there points in the code the reviewer needs to double check?
no

## Why was this MR needed?
Unexpected behavior as a user

## What are the relevant issue numbers?

## Screenshots (if relevant)

External Users

The user has the rights of a public user execpt it can never create a project, group, or team. Also it cant view internal projects.
