InstrumentationAbstract#getConfig should return the type of the concrete instrumentation

[Flarna]

Is your feature request related to a problem? Please describe.

Quite a lot instrumentations extend the config. The protected _config: types.InstrumentationConfig; member is accessible to them but it misses the extra configuration options.

Describe the solution you'd like

The type returned by getConfig and accepted by setConfig should be that one from the concrete instrumentation (defaults to types.InstrumentationConfig if not specified).

Describe alternatives you've considered

• downcast as needed
• add a member in concrete instrumentation with concrete type (like here)
