Support the DefaultAzureCredential for built-in connectors

[KillianPLG]

Supporting the DefaultAzureCredential for Service Bus, HTTP, and API Management connections would go a long way toward making Logic Apps (Standard) truly local-development friendly. There are probably other connectors that would benefit from this, but those are the main ones that I use. For example, the various Azure Storage connectors (blob, table, file) and Event Grid would probably also benefit. Pretty much anywhere that oAuth2 or Managed Identities are supported would be a great place for the DefaultAzureCredential.

One of the big problems that developers face when developing locally is that we have to make connection changes between local debugging and deployed logic apps. If we could rely on the DefaultAzureCredential to choose the correct token for us, local development becomes a lot easier.

This is very similar to a discussion topic I created over two years ago, #715 . No response from anyone at Microsoft. This change would make a huge improvement to the local development experience.
