Adding Active Directory Default support

[Benjin]

Description

Adding support for authentication via ActiveDirectoryDefault mode, which instructs the MDS driver to look for a credential on its own in a number of different places, including Az powershell, Az CLI, a shared token cache, and environment credentials (which covers client ID + secret/cert and username + password).

To test, install the Az CLI, then run az login to sign in with an account.

To do:

• update with SQL Tools Service build that includes Adding Active Directory Default support sqltoolsservice#2646

Code Changes Checklist
