fix: Add logging to AbstractMethod.execute

[SMadani]

This PR removes declarations of Apache Commons loggers and adds log statements for requests and responses made using the SDK, using java.util.logging with INFO level. This is all centralised in AbstractMethod#execute(T) for simplicity.

EDIT: Also added non-static logging to DynamicEndpoint so each individual endpoint implementation can have its own logging of raw request and responses prior to (de-)serialisation.
