User Story:

As an installer dev, I want to be able to:

• use azidentity for auth
• use v2 clients 

so that I can

• not use deprecated adal
• authenticate directly with creds from azidentity 
• use newest clients

Acceptance Criteria:

Description of criteria:

• Session allows auth with creds
• Consideration for Azure Stack and GovCloud, which at the moment don't support auth with azidentity but hopefully will by 4.12
• Use of any stable v2 clients

(optional) Out of Scope:

Detail about what is specifically not being delivered in the story

Engineering Details:

• #5665 was merged but reverted after the delay was announced
• V2 clients live in /sdk
• V2 client stability dates captured here: https://azure.github.io/azure-sdk/releases/latest/index.html#go
• Significant detail captured in preceding card CORS-1910
