Delete source branch on merge

[tapaszto]

This is a new feature for Azure DevOps which allows configuring the deletion of the source branch on merge according to the values in the server config and repo config.

Sample server config:

repos:
- id: /.*/
  workflow: default
  allow_custom_workflows: false
  allowed_overrides: [delete_source_branch_on_merge]
  delete_source_branch_on_merge: true

Sample repo config:

version: 3
automerge: true
delete_source_branch_on_merge: true
projects:
- name: my-test-project
  dir: .
  terraform_version: v0.11.0
  delete_source_branch_on_merge: true
  autoplan:
    when_modified: ["*.tf", "../modules/**.tf"]
    enabled: true

delete_source_branch_on_merge is optional in all level, the default value is false if it's not defined in a level
valid values: true | false | not defined

Hi @nishkrishnan & @lkysow,
I performed the requested modifications, can you approve the PR please?

@nishkrishnan & @lkysow,

Please review this. This is the only change we need to get back to the official Atlantis instead of having our fork internally.

Thanks!

@tapaszto sorry for the delay here. The code changes look good, could you resolve the conflicts in project_command_builder.go and then we can move this forward.

@nishkrishnan, @acastle, @lkysow Could you guys please take a look ASAP? We would like to merge this finally.

Thanks!

@nishkrishnan, @acastle, @lkysow any update? We needed to merge in updates multiple times by now, we cannot continue this forever. Please review and merge this, it should be up to date now for a merge.

@nishkrishnan, @acastle, @lkysow, guys, can you approve this PR please? Keeping this branch up-to-date and update it whenever the master is changed is an extreme overhead for us. Our primary goal is using the official community Atlantis releases instead of our own internal fork. Using Atlantis is a strategic decision regarding our Azure IaC deployments within the company
