Fetch all branch names of a repo (Something like fetch_tags for branches)

Is your feature request related to a problem? Please describe.

Problem : While using git resource get, it fetches only supplied branch name. This makes it difficult to perform certail operations like rebase on top of another branch.

Describe the solution you'd like

A new param named "fetch_branches" can be added. This will fetch all branches from upstream. (git fetch)
