Now that we add an event when logging errors, we need to avoid passing an
exception object directly to the logger. Otherwise we end up adding the
unserializable Exception object to the events list, which causes an error when
trying to write the output.
Add ContextLogger wich extends logging.Logger's warning and error
methods to automatically add the message to the context's events (if a
context has been provided).
devlib's CGgroups module logs things at INFO level. The information it
logs is too detailed for what WA considers "INFO", and should be logged
at DEBUG level instead.

Also moving core target implementation stuff under "framework".
