.SYNOPSIS
    Uses the TFS REST API to apply branch policies to specified branch
.DESCRIPTION
    This script uses the TFS REST API for configurations to set branch policies for:
    -approver group
    -Minimum approvers (2)
    -Required build
    -Work Item required
.NOTES
    -Branch is set via build definition variable at queue time
#>
