[Bug] az repos ref create

[t3mi]

Describe the bug
az repos ref create should exit with non zero exit code when it could not complete the action instead of exiting with 0 and showing the error:

{
  "customMessage": "TF401027: You need the Git 'CreateBranch' permission to perform this action. Details: identity '<guid>\\email', scope 'repository'.",
  "isLocked": false,
  "name": "refs/heads/branch1",
  "newObjectId": "05abcd2cfc888fccc25b132bb777d84b84d169a8",
  "oldObjectId": "0000000000000000000000000000000000000000",
  "rejectedBy": null,
  "repositoryId": "<guid>",
  "success": false,
  "updateStatus": "createBranchPermissionRequired"
}

To Reproduce
Azure Cli Version:

azure-cli                         2.21.0 *

core                              2.21.0 *
telemetry                          1.0.6

Extensions:
azure-devops                      0.18.0

Steps to reproduce the behavior:

1. Remove Create branch permission for the identity from the repository.
2. Try to create a branch with that identity.

Expected behavior
az exits with non zero exit code.

• Time taken to come up with proposal and timeline : 0.5 day

Proposal

We can check if failure reason is 'createBranchPermissionRequired' or 'createTagPermissionRequired'
We can change the status to success

Expected timeline

implementation - 0.5 day - 16 Aug
unit test - 1 day - 17 Aug

@roshan-sy : thanks for the detailed proposal 😄

I will suggest to take dependency only on response.success

if response.success is false:
  raise new CLIException(response.message)

because I belive the ask from customer is to not return 0 (success) in case operation failed on ADO service side.
