Add xz-compressed archive indexes

Bug Description

We currently only provide {Packages,Sources,Translations-*}.{gz,bz2}. xz is generally a better compression format than bz2 and is usually preferred by Debian these days. I'd like to add xz support, and preferably drop bz2 support not too long afterwards.

We should also think about whether this applies to old series, or just >= xenial; my instinct is the latter, not least because we'd want to drop .bz2 fairly soon afterwards and that seems excessively intrusive for old series. But continuing to widen DistroSeries with even more boolean columns seems messy. How about perhaps adding a publishing_options (or similar) JSON column? We could then turn backports_not_automatic and include_long_descriptions into properties using that; those are only used by the DistroSeries webservice export, InitializeDistroSeries, and the publisher, and there's no need for them to be indexed or anything. That would make it easy to configure this kind of feature for this case and for the future.

This is deployable and adding xz to index_compressors will work, but we need to deploy before removing bzip2.

xenial now has xz indexes and no bz2 indexes.
