improve pylint; generate errors and config in sorted order

Since the config is not in a deterministic order makes it hard to
compare two config's and see what changed. Personally, I'm not
positive I understand this use-case; i.e. you have an existing config
file, you save it, and then rebuild and then diff the two files. I'd
have thought you'd just run check and the output of the tool was the
diff.

I however do see the value in sorting the file so that when someone
submits a change that includes a change to the config, reviewers can
see more easily what the change is doing.

Similarly, the output from pylint (errors) are generated one file at a
time and os.walk makes no guarantee of deterministic order. So we
should collect all errors (across all files) and then print an ordered
list for human consumption.

The intent is also to make pylint voting soon (in master). the changes
to contributing.rst and tox.ini are to make that easier. The config
file has also been sorted in place.

This change was motivated by an email exchange with Peter so I am
marking him as a co-conspirator.

The line numbers were removed from the tools/trove-pylint.config file
as these would change whenever the line numbers in the file changed
(since they are currently not being used in the comparison; they can
be re-added if deemed necessary at the cost of having every 'rebuild'
run create a different file).

The tools/trove-pylint.config was regenerated as well, since the
remaining two errors seem to be innocuous:

  ERROR: trove/taskmanager/manager.py 392: E1101 no-member,
  Manager.upgrade: Instance of 'BuiltInstance' has no 'upgrade' member
  (new method introduced by instance upgrade; other BuiltInstance
  member errors are already ignored.)

and

  ERROR: trove/guestagent/datastore/experimental/postgresql/service/
  access.py 80: E1101 no-member, PgSqlAccess.list_access: Instance ofi
  'PgSqlAccess' has no '_find_user' member
  (this is due to the fact that PostgreSQL is spread over multiple
  files and pylint should cease to complain once
  https://review.openstack.org/#/c/346082/ lands.)
