Fixes #123

This basically removes loader.py (uses entry points instead) and all the calls for set_preferred_implementation* in order to cleanly separate user code from configuration. It introduces a configuration manager that can have configuration set by a configuration file (for the moment just a JSON file, probably a more suitable format would be ideal) or environment variables that override the former configuration method.

A couple test environments are still failing (mypy and tracecontext). Opening still to receive input.

LGTM, but two questions:

I see examples that used to call set_preferred_implementation with an SDK object don't call set_provider now. Is this because you expect users to set the SDK objects in config instead? If so we probably need to include that in the docs.

Many tests set providers, but don't unset them. It looks like this isn't a problem in practice because tests that rely on a certain provider set it themselves, but we should avoid side effects like this.

This returns an api DefaultMeter now instead of a sdk Meter, shouldn't we have this line above?

metrics.set_meter_provider(sdk.metrics.MeterProvider())

Or is it intentional that the examples only use the API types? I think it'd be more helpful to show using the SDK since that's how most users will do it.

It seems like tests that set the meter/tracer provider on setup should still unset it on teardown. Why remove this instead of update it?

This should be done before L42, otherwise the returned tracer will be de default one. I pushed a fix as a part of a747b61.
