Remove Old Style Tracker and db/backend_name support (was: Is anybody using config.py rather ...)

Hi all:

Earlier I wrote:

It turns out that the support for old style trackers which had the files:

  config.py - replaced by config.ini in new style trackers
  dbinit.py - replaced by schema.py in new style trackers (if present
              the tracker is an old style tracker).
  select_db.py - replaced by db/backend_name then RDBMS_BACKEND in config.ini
  interfaces.py - still around

is still in the code base in instance.py. To go along with removal of
support for config.py from configure.py, I propose removing the
OldStyleTracker class from instance.py. This also removes another:
'import imp' from the code.

Also the obsolete db/backend_name file was replaced by RDBMS_BACKEND in
config.ini in release 1.6. The code that supports it has a comment to
delete support in revision 1.7 of roundup. That would be the minor rev
after 1.6 which turned out to be rev 2.0. So I would like to nuke that
support as well.

Does anybody have a problem with removing this dead code? (Hopefully
with the removal of this old untested code I can get to 70% code
coverage 8-).)

Have a great week.
