title of release needs to be include in the stream

[Blake Rouse]

Currently MAAS pulls the title of the operating system from distro_info, this information should come from simplestreams instead. This would make it much easier to show a nice title for a release and would not require MAAS to use distro_info. Sometimes distro_info can be out of sync with the current images in the stream, causing the images not to show up in MAAS.

please give example of 'title'
  14.04 ?
   15.10
  14.04 Ubuntu LTS ?
what do you want.

Currently MAAS shows "Ubuntu 14.04 LTS "Trusty Tahr" for 14.04. It might be good to split up the release number and the release name.

os_title = "Ubuntu"
release_title = "14.04 LTS"
release_code_name = "Trusty Tahr"

probably "codename" is fine don't need "release_code_name"

Trusty values are like:
 'release': 'trusty',
 'release_codename': 'Trusty Tahr',
 'release_title': '14.04 LTS',
 'version': '14.04',

I'm gonna mark this fix-released based on that data.
