Registration methods for EventStore TCP+gRPC passing in the ServiceProvider

[NielsPilgaard]

What this PR does / why we need it:
This will allow creation of connection string to change depending on configuration.

I also fixed a test that was green for the wrong reason, and added TaskCreationOptions.RunContinuationsAsynchronously to a TaskCompletionSource. Let me know if you'd like these changes removed and/or put in a different PR.

Which issue(s) this PR fixes:
Not having access to the service provider when making a connection string.

Please reference the issue this PR will close: #1531

Hi @sungam3r . I'm not able to regenerate a new api key now, but i will manage it with someone else and update the secret. I will reply here as soon as i get it. Thnx.

Hi @sungam3r , the new updated api key is set on the repository. I have re-run the build and it worked. Thank you both (+@unaizorrilla ).
