Transient "Service principal does not exist" error in Azure Gov

[sstjean]

Description
When running mlz_tf_setup.sh in Azure Government, the service principal throws occasional errors. Either the SP wasn't created or it wasn't fully created by the time the code goes to grab the AppId. In either case, the script fails. This may be an area of code where we want to add a retry or sleep to give AAD a chance to complete.

Steps to Reproduce
Steps to reproduce the behavior:

1. Run mlz_tf_setup.sh in MAG

Expected behavior
SP is always created

Actual behavior
SP is sometimes created, sometimes created but the code can't retrieve the AppId and sometimes creation fails.
