[RFE] provide OSC baremetal help documentation

[Ruby Loo]

We should provide documentation for our OSC baremetal plugin (by taking the 'help' text).

Octavia has it, so should we! https://docs.openstack.org/python-octaviaclient/latest/cli/index.html

Dmitry and I weren't sure if this is an RFE or not, regardless, if it is, I approved it :)

    Add auto-generated CLI reference

    The Ironic OSC plugin CLI was not being fully documented.

    This patch enables an auto-generated CLI reference for the OSC plugin.

    Note: There is a formatting issue with required arguments that include a
    hyphen. This has been opened as a bug [1].
