Merge lp:~wgrant/ubuntu-archive-publishing/ls-lR into lp:ubuntu-archive-publishing

[William Grant]

Generate ls-lR.gz in run-parts rather than the core LP publisher, so we can trigger proposed-migration immediately after the dists switch.

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.

This branch adds ls-lR generation to finalize.d, so we can remove it from Launchpad. The proposed-migration trigger will be added later.
