Want to add that I haven't been able to test this fully on my side yet.

make sure we initialize before invoking get_credential()

This is still a late runtime error that I was trying to turn into a config load error in #819

Alright, I made a new change to #819 to handle that now.
From what I can tell the rest of this one is good, but it'd be good to get confirmation that DefaultCredential doesn't need refreshed, especially with the SP part.

To use token-based authentication for
ShareClient, I think we should be passing in the credential object derived fromTokenCredential(in our case, some instance ofDefaultAzureCredential.Previously, we were passing specific string tokens to the
credentialargument, which is being intepreted as a SAS token.This leads to errors like:
azure.core.exceptions.ClientAuthenticationError: Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.ShareClient documentation on the
credentialargument.By passing in the whole
TokenCredentialobject, I believeShareClientwill manage the token lifecycle and we won't need to do so as mentioned in #818.
