Add support for different dependency lifetime

[msmolka]

I would like to have singleton for authentication client as in most cases never changed during application lifetime.

This isn't considered good practice as we're using the IHttpClientFactory pattern. The client is designed to be short-lived as the internal handler is pooled. See https://learn.microsoft.com/en-us/dotnet/core/extensions/httpclient-factory#httpclient-lifetime-management
