While we have the OSI classifier for "MIT License", it looks
like for the "license" field, this is normally just the word
"MIT" and not "MIT License".   While the pypa docs suggest we
only need it as the OSI classifier, keep it also in "license"
in order to appease common tooling.

Applied on top of a pure run of black -l 79 in
I7eda77fed3d8e73df84b3651fd6cfcfe858d4dc9,  this set of changes
resolves all remaining flake8 conditions for those codes
we have enabled in setup.cfg.

Included are resolutions for all remaining flake8 issues
including shadowed builtins, long lines, import order, unused
imports, duplicate imports, and docstring issues.

This is a straight reformat run using black as is, with no edits
applied at all.

The black run will format code consistently, however in
some cases that are prevalent in SQLAlchemy code it produces
too-long lines.   The too-long lines will be resolved in the
following commit that will resolve all remaining flake8 issues
including shadowed builtins, long lines, import order, unused
imports, duplicate imports, and docstring issues.

Fixes to the test suite, a few errant imports, and setup.py:

- mysql and postgresql have unused 'json' imports; remove
- postgresql is exporting the 'json' symbol, remove
- make sure setup.py can find __version__ using " or '
- retry logic in provision create database for postgresql fixed
- refactor test_magazine to use cls.tables rather than globals
- remove unused class in test_scoping
- add a comment to test_deprecations that this test suite itself
  is deprecated
- don't use mapper() and orm_mapper() in test_unitofwork, just
  use mapper()
- remove dupe test_scalar_set_None test in test_attributes
- Python 2.7 and above includes unittest.SkipTest, remove pre-2.7
  fallback
- use imported SkipTest in profiling
- declarative test_reflection tests with "reflectable_autoincrement"
  already don't run on oracle or firebird; remove conditional logic
  for these, which also removes an "id" symbol
- clean up test in test_functions, remove print statement
- remove dupe test_literal_processor_coercion_native_int_out_of_range
  in test/sql/test_types.py
- fix psycopg2_hstore ref

Swing the biggest hammer, run multiprocessing.Process() for
each memusage test individually so that they are fully isolated
from the parent process and any side effects of pytest-xdist

Also add --nomemory as a shortcut to exclude_tags=memory-intensive
and add this to the setup.py test runner as the memory tests
should not be running for quick runs
