Leverage the new cliff command class attribute (_description) to get the help of a command, this allows us to mark strings for translation. We could not do this before since the help was grabbed from the docstring. This also depends on a new release of cliff and a bump to the minimum level in osc's requirements. Closes-Bug: 1636209 Depends-On: Id915f6aa7d95a0ff3dc6e2ceaac5decb3f3bf0da Change-Id: I8673080bb5625e8e3c499feaefd42dfc7121e96f
