It has been necessary to manually keep the OSA connection plugin
module options matching those in the builtin ssh connection plugin
that it is derived from. It is possible for differences to
accumulate over time as ansible versions are updated and this can
lead to errors, and difficult using the plugin with different versions
of ansible.
This patch uses the "documentation fragments" ansible feature, but
instead of statically defining the options in the fragment, the
builtin ssh connection plugin is loaded and the options section from
the DOCUMENTATION string is extracted and re-used.
