Update installation instructions to include stable/ocata branch

This change updates the undercloud installation and overcloud
basic command line installation instructions to include repos
for the stable branch of Ocata.

It appears that all the required information for upgrading from
Newton to Ocata already appears in the post_deployment/upgrading
document, but this should probably be reviewed.
