TA-4066: Implement git integration

[ZgjimHaziri]

Description

Implemented git integration based on this PoC and this spike doc.
Changes from the initial design:

• Renamed back to git from vcs after the feedback we got and the research that git is mainly used by a large margin.
• Marked the commands and options as beta.
• Fixed minor issues
• Changes in the push to branch functionality,
  • Fixed how it behaves when checking out on new branches that don't exist in the remote.
  • Now it cleanups the directory and pushes the new changes, in order to avoid having multiple directories (because of the version in the directory name) when we have exported new versions.

Bumped the minor version since it's a new feature being added.
