Use github access token for git mirroring

[2017029570]

Hello,

The official document describes that there are 2 ways to authenticate to access git repository when git mirroring, which are password-based authentication and OpenSSH key.

However, I wonder if we could use github access token as authentication key

Hi, @2017029570 that's a good suggestion!
We definitely need to support accessing GitHub using an access token.
