feat: support github enterprise api

[ricardojdsilva87]

Pull Request

Proposed Changes

This Pull request is based on the already merged github-community-projects/evergreen#256 to give support to GitHub Enterprise login using a GitHub App also created on GitHub Enterprise

• Added the file .coveragerc to ignore the python test files, because of that the coverage went below the limit of 60% and still need to check if there is the possibility to add tests for the open_contrib_pr.py code

LGTM just one question

failing CI. Just saw it. Code looks good otherwise.

RE: test failure. Test coverage is too low.

If @jmeridth you feel like the added code has decent coverage for what was changed we can bypass this check. I'll open a new pr to add some tests. Looks like one file has 0% coverage.

I'm comfortable for us to merge this. @zkoppert you?
