Deployment metadata to be added

## Scenario:
When checking at a deployment on a subscription, it is hard to tell how, when and which code was used to deploy a particular TF environment.

## Proposed solution:
For each tfstate file on Azure storage, we plan to add in the Azure blob metadafa, the following fields:
- [ ] Version of rover used
- [ ] Rover_logged_in user that deployed the environment
- [ ] Checksum of commit
- [ ] Source repo
- [ ] Branch version
- [ ] Checksum of the commit
