Bug 1099573 Add Quantum metadata proxy documentation

Document metadata_agent.ini - includes auth_* and admin_* flags needed for
the Qauntum client as the metadata agent does not seem to be able to read
these from quantum.conf even though it is on the command line.
Removed section in advanced config options about the need for additional
routing as this no longer applies.

Separate/Link compute config sections

To avoid double maintenance during the documentation restructure
effort, and to further facilitate content sharing, this patch
separates some sections of the compute configuration chapter
into separate files.

Separates vnc into 'using' and 'configuring'.

Add some status notes.

  Then remove the interfaces from the router:

Bug # 1197054 - Added new official fedora cloud image link.

Fedora now includes 'official' cloud images, rather than the
unofficial ones provided in earlier releases. As such I have
updated the relevant paragraph to link to these.

Added EPEL repository to instructions and modified RDO instruction to
