Support for repos[*].branch field in server side repo config

[enummela]

The example from server side repo config docs indicates that it's possible to use regex matching on pull requests by their base branch:

# branch is an regex matching pull requests by base branch
# (the branch the pull request is getting merged into).
# By default, all branches are matched
branch: /.*/

However, when I specify a branch field in the server side repo config like this:

data:
  repos.yaml: |
    ---
    repos:
    - id: /.*/
      apply_requirements: []
      branch: /^staging$/
      workflow: default
      allowed_overrides:
        - apply_requirements
      allow_custom_workflows: true

Atlantis throws this error:

Error: initializing server: parsing /etc/atlantis/repos.yaml file: yaml: unmarshal errors:
  line 5: field branch not found in type raw.Repo

Output of atlantis version:

atlantis 0.16.1

The server side config works when the branch field is not specified. Could someone please take a look and confirm if branch field is supported or else point out where I went wrong 😅 ? Thanks in advance!

Digging into this a bit more, it looks like the branch matcher functionality was merged in #1383 but hasn't made it into any of the releases yet. Fingers crossed this gets into the next release because for our use case it's quite critical.

ditto @enummela we must be able to use something like branch: /^(master|main)$/
