This removes the check on in tree sample generation to ensure the file
matches the config options. However, to counter the loss of the in-tree
the tempest init command will now automatically generate a new sample
config in the local etc dir when run. This will include all of the oslo
options that were previously included in the in-tree sample file.
Additionally, the docs now contain the complete text of the generated
sample output. These also get published on docs.openstack.org on each
commit to tempest. Between this 2 alternatives there shouldn't be a need
to keep the file in tree anymore, especially given the weekly headaches
with new oslo releases changing the config option help breaking the job.
