Code review comment for ~vorlon/ubuntu-seeds/+git/lubuntu:muon-decay

Per tsimonq2 in #ubuntu-release: > I'd like to hear RikMills' thoughts but preliminary ack.

Corresponding response by RikMills: > vorlon tsimonq2: it is completely unsupportable for a release now, so gotta go IMO

Per Lubuntu Developer discussions: if it's deprecated, gone, and needs to die, then we should drop Muon in Lubuntu and use Discover instead as it's stated as the replacement.

Steve pinged me in #ubuntu-release for my opinion, and after review now that i have stable connectivity for a short while in my travels for work (and the return journey!), it is my opinion that we should drop muon because we have Discover. This can be revisited in future if necessary.
