Allow scan directories to be Profile aware

[cspray]

Annotated Container is intended to be a fully-featured dependency injection container. That means, providing testing utilities to help with integration and acceptance testing using the container. With this type of testing it could be desired to change or alter services based on being in a testing profile; consider a LoggerInterface that outputs to normal locations in dev, but uses testing implementations if in test. While this works out-of-the-box, if the directory the test logger is in is not present or the autoloader does not include dev dependencies, a likely occurrence in production environments, a problem is encountered. Ultimately, if we scan a service, in this case a test logger, it must be loadable and it isn't.

Realistically, the only way to deal with this problem is to simply not scan the directory with the test service when you're in a profile that doesn't need it. This would also have the benefit of reducing the amount of files needing to be scanned when running in production environments.

This is a fairly significant change; more than 1 corresponding piece will need to be made profile-aware and a former list of scalar strings must now become a complex object capable of holding multiple pieces of information; the directory and any profiles it may be associated with.
