HttpClient Retry via PowerBiClient

[chsowald]

Hi.  I'm using Polly to easily enable HttpClient retries for transient errors.  This is easy when using the standard HttpClient.  I'm getting PowerBI embed tokens on my backend, but don't see a way to enable Polly retries for the PowerBiClient as I can't pass it an HttpClient, though it appears to use one internally.

Is there a way to override the default HttpClient when creating the PowerBiClient or can you add one?  Sadly, I can even get (but not set) the HttpClient on the PowerBiClient.  So close!
