This change reduces some unnecessary complexity in the library, Redis commands do not change much after all. Developers can still implement their own commands factory, inject new commands or override existing ones. The "profile" client options has been renamed to "commands" and it accepts instances of Predis\Command\FactoryInterface. The test suite checks at runtime the version of the running instance of Redis for integration tests to adapt itself automatically.
