Comment 4 for bug 1337437

Been looking into removing the enum from UbuntuOS. If we pull this information from simplestreams, then we would need to use the daily channel, because its the only channel that contains Utopic. get_supported_releases needs to return all available release, not just the ones boot images are present.

Also the simplestreams data does not provide a nice title for the release, it only uses the codename. We would also need to use python-distro-info to get the fullname of the release to present to the user on the WebUI.

What is the benefit of pulling the data from simplestreams for the available releases, when python-distro-info already contains all of the data we need on the system? Just want to make sure I implement it correctly.

Also if we go with the simplestreams approach, we would need to cache the data, as we should be making a web request everytime MAAS ask for the available releases for the operating system.
