Support more fields of the git repository CR

[LinuxSuRen]

Currently (since v3.3.0), a git repository could only store the URL of a repository. It's not easy to get all information. for example the owner or repository name.

There're two possible solutions to improve it:

• Add field to the spec
• Put those information to the annotations
