Move code and ensure proper requires

General things concerning AeolusClient namespace are moved to
aeolus_client.rb.

Logging configuration that is done by requiring aeolus_client/base.rb is
marked as FIXME for removal when configuration refactoring is done.

Require aeolus_client/base.rb for resource classes that inherit from it.
