Most of the drivers require extra requirements. This adds these to
the extras field in setup.cfg so that users can more easily install
extra requirements.
Also removes the lower-constraints.txt file because we already removed
tests of l-c by [1].
Note that the lower versions of SQLAlchemy and oslo.messaging are
picked up from requirements in the other repos, and further lower
versions might be allowed.

OSProfiler -- Library for cross-project profiling
OSProfiler provides a tiny but powerful library that is used by most (soon to be all) OpenStack projects and their python clients. It provides functionality to be able to generate 1 trace per request, that goes through all involved services. This trace can then be extracted and used to build a tree of calls which can be quite handy for a variety of reasons (for example in isolating cross-project performance issues).
