Disables XML publishing

Address the change from XML to RST, XML based jobs are disabled. Current
content in Juno release for training guides is not going to include any
XML Docbook content. This patch disables the XML related jobs.

This patch will be followed by more jobs added to build RST content to
HTML and PDF format as required using the tools decided by the team. The
jobs disabled will be re-enabled with the appropriate set of tools.

Deletes all the jobs which are not required. Addresses changes done by
https://review.openstack.org/#/c/152118.
