Add ADFS / Azure Stack Support

[joshfree]

• On-prem active directory instance support

• Requested by CLI / PSH for .NET and Python

• ClientSecretCredential and CertificateCredential (Client secret and certificate credentials use MSAL ConfidentialClientApplication #13215)

• SharedTokenCacheCredential (SharedTokenCacheCredential uses MSAL when given an AuthenticationRecord #13490)

• user credentials (DeviceCodeCredential, InteractiveBrowserCredential, UsernamePasswordCredential)

• async credentials (waiting for async support AzureAD/microsoft-authentication-library-for-python#88)

I'm removing the blocking-release tag because the work needed for 1.5.0b1 is complete, but leaving this open on the backlog to track the remaining work of adding ADFS support to async credentials.
