Support snap channels

[Robert Ancell]

[Impact]

[Test Case]
1. Open GNOME Software
2. Select the VLC snap

Observed result:
No channel information is shown.

Expected result:
The snap is shown with four (at the time of writing) channels available - stable/candidate/beta/edge. You are able to choose a channel at the time of install and this installs the appropriate version (can be confirmed with 'snap info vlc' on the command line). Once installed the channel can be changed and the snap updated (requires clicking install again).

[Regression Potential]
Patch is quite large and could cause new bugs.

Please be sure to prepare an artful update for this. Also, to ease the SRU team's work, could you point to at which version has the same bug been fixed in bionic? (it's hard for us to look to that in package history when it's not connected to this particular bug number)

Hello Robert, or anyone else affected,

Accepted gnome-software into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gnome-software/3.20.5-0ubuntu0.16.04.10 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

On a fully updated Xenial VM with -proposed enabled I can see channel information for VLC.
