Alexander Chadin cfb9e6b5b0 Add support for watcher osclient and watcher related types
This patch set registers Watcher as Service for Rally and
adds Watcher Goal and Strategy Types with related unit tests.

Also it adds *.DS_Store type to gitignore and python-watcherclient
to the requirements.txt to support Watcher in future.
