Merge lp:~wgrant/launchpad/please-dont-generateListings into lp:launchpad

[William Grant]

Drop ls-lR.gz generation from publish-ftpmaster, as it's now done by lp:ubuntu-archive-publishing. This is mostly to let finalize.d trigger proposed-migration moments after the dists switch, rather than waiting for ls-lR to complete.

We want to trigger proposed-migration as soon as Launchpad performs the dists switch. Rather than adding a new run-parts hook, we'll reuse finalize.d and move the expensive bit between the dists switch and finalize.d (ls-lR generation) into a later step of finalize.d.

https://code.launchpad.net/~wgrant/ubuntu-archive-publishing/ls-lR/+merge/215916 adds the new hook to finalize.d. This branch removes the built-in Launchpad ls-lR generation.

Great job!

finalize.d is excellent for accommodating *specialties* like this.
