Convert grpc-js plugin to instrumentation

[obecny]

• Change folder name from opentelemetry-plugin-* to opentelemetry-instrumentation-*
• Change package name from @opentelemetry/plugin-* to @opentelemetry/instrumentation-*
• Change implementation to use InstrumentationBase

I'm currently porting the grpc plugin and i was wondering if we could do the same as http/https and migrate both in one instrumentation ? This would remove the need of a package to share tests.

WDYT ? cc @obecny @dyladan

Can both plugins exists without each other in production ? if so I would not merge them.

They can, however in the near term grpc will be deprecated in favor of grpc-js. Also since we can instrument multiple modules at once i think it should handle both of them, it would reduce the code duplication between both packages and smoothly handle people upgrading from grpc to grpc-js

It makes sense to merge it then .
