Implement unittests for all methods in clients lib, even if they are part of greater functionality.

Missing tests:
- Some unittests test the rest-api-aware client commands, but miss the kamaki-client aware commands
e.g. there is a unittest for container_post or object_put but not for upload. Upload is tests in container_post and in object_put.
- There are also other cases, where convenienve calls are tested, but rest-api-aware calls are left untested
- clients.utils and clients package methods are also untested (since they are called by tested components) and should be tested individually
- connection module should also be tested individually
