Chris Dent d4d9457aa1 Use expanding bindparam in provider_ids_from_rp_ids in_ 
This was explored as part of discussion with zzzeek on various
ways to make a statement with a large in_ be more performant.

Batching the queries by chunking rp_ids did not help, but an
expanding bindparam did: it makes the surrounding method about
50% faster [1].

bindparam expanding was added in sqlalchemy 1.2.0 so we bump
the requirements here to the latest 1.2.x bugfix release,
1.2.19.

[1] With the caveat that profiling and benchmarking are very
different things, and in this case it is profiling results
which are being analysed.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
