Merge lp:~cjwatson/launchpad/db-snap-channels into lp:launchpad/db-devel

[Colin Watson]

Add Snap.store_channels column.

Add Snap.store_channels column listing the channels (if any) to which a snap package should be released after a successful upload. This will just be a JSON-encoded array; we don't need anything more complicated.
