feat(instrumentation): add createInstrumentation factory function

[david-luna]

Which problem is this PR solving?

this PR add a factory function to create instrumentations. the factory function has a single param to get an object that implements the InstrumentationDelegate interface. The factory function wraps the delegate and takes care of the enabling or disabling the instrumentation (interaction with RITM and ITM).

This approach removes the inheritance from InstrumentationAbstract -> InstrumentationBase avoiding any initialisation issue in the constructor as it happens in #1989.

with this change we will have two ways of creating instrumentations:

• extending InstrumentationBase
• calling createInstrumentation function with a delegate

IMHO the path should be to sunset the former in favour of the later so we avoid the init issue in all instrumentations and also simplifies a bit the instrumentation code.

Fixes #1989

Short description of the changes

• added a new function createInstrumentation in instrumentation package for node
• TODO: added a new function createInstrumentation in instrumentation package for browser
• created aHttpInstrumentationDelegate class and export createHttpInstrumentation function in http instrumentation
