[Datafactory] Fix Azure/azure-cli-extensions#10001: az datafactory trigger start: Retry on provisioning error instead of failing immediately

[Copilot]

az datafactory trigger start throws BadRequest: Resource cannot be updated during provisioning when the trigger (e.g. created via Terraform) hasn't finished internal provisioning. The CLI previously surfaced this opaque service error with no recovery path.

Changes

• manual/custom.py — Overrides the generated datafactory_trigger_start with retry logic:

  • Catches HttpResponseError where the message contains "Resource cannot be updated during provisioning"
  • Retries up to 10 times with a 30-second delay (~5 min total), logging a warning each attempt
  • After max retries, raises a CLIError with an actionable message naming the trigger
  • All other errors are re-raised immediately without retry

• manual/tests/latest/test_datafactory_trigger_start_unit.py — New unit tests covering: immediate success, retry-then-succeed, max-retry exhaustion → CLIError, non-provisioning errors bypass retry, --no-wait flag passthrough

• HISTORY.rst / setup.py — Version bumped to 1.0.5
