Added Enrich Handlers similar to AspNetCoreTraceInstrumentationOptions and the option to filter and create activity with each invocation context.

Still need to do some testing, but before spending too much time, I want to double check if you agree with this approach. The library works well, so hats down for the work done so far, but I've felt the need of :

• some extensions points where I can alter the current activity based on the invocation/result
• the ability to filter out some activities/spans, as with Blazor Server hosting approach, it is a bit noisy to see "ComponentRendered" messages
• with Blazor Server, all the spans seem to be descendants of HubConnectionContext.OriginalActivity, which on long lived sessions makes debugging very difficult

Thank you for the PR.

• with Blazor Server, all the spans seem to be descendants of HubConnectionContext.OriginalActivity, which on long lived sessions makes debugging very difficult

These demands make sense, so I will support them. However, I am not satisfied with the changes made to this PR in several respects, so I am closing it.

Sure, this was something quickly put together just to POC that it is doable before reaching out. Do you have availability to make these changes in the near future? And, if so, could you tag me when you merge the changes so I can get the latest version? Thanks !

These two points were supported from v1.6.0. Try it!

@nenoNaninu will give it a try, thanks ! might be some time until I can do it though, had to switch my focus to something else
