[FEATURE/PERFORMANCE] Search Client AzureKeyCredential request aggregation #46663

Please describe the feature.

While stress-testing our search solution we have discovered an issue with HTTP requests. It occasionally makes up to ~50 requests at once to https://login.microsoftonline.com/{UUID}/v2.0/.well-known/openid-configuration which causes severe performance issues.

In our setup we have a singleton SearchClient in ASP.NET.

Our hypothesis is that this is during authentication renewal and that there is a missing request aggregation in the SDK, causing all new searches until authentication is renewed to trigger a new separate HTTP request to authenticate.
