Instrumentation Adapters to support Activity API (#701) 

* use the same activity created by existing instrumentation. Simply enhance it.

* remove sampling from instrumentation

* add asp.net core instrumentation

* move sampling to Instrumentation for now.
Make Asp.Net instrumentation work with Activity API

* Add httpClient .net core instrumentation

* Ad SqlClientInstrumentation

* remove sqlclientinstrumentation from previous instrumentation

* Quick implementation for AzureClients - not validated as there are unit tests and this is not planned to be in this repo as well.

* fix examples

* fix sampling flag

* made sample app work with jaeger

* Mark todos and fix AspNet tests

* Fix asp.net core tests and mark TODOs

* Add TODO for httpclient .net core test and fix test

* add todo and fix httpclient test

* add todos and fil sqlclienttests

* Make OpenTelemetrySDK disposable and take care of disposing all ds subscriptions.

* Added OpenTelemetry.Default instead of static method

* AspNet, AspNetCore fix Dispose issue

* stylecop stuff lost i merge
