db: Replace use of deprecated API

Browse Source 
We were missing a number of users of SQLALchemy APIs that were either
changed or removed in 2.0. These were yielding the following errors in
2.0.

  TypeError: MetaData.__init__() got an unexpected keyword argument
  'bind'

  TypeError: TableClause.insert() got an unexpected keyword argument
  'values'

  TypeError: TableClause.update() got an unexpected keyword argument
  'values'

  AttributeError: 'Engine' object has no attribute 'execute'

Resolve these issues. We will fix the test class issue in a follow-up.
