alembic: Add missing queue and CDR table creation scripts.

* Added the queues and queue_members tables to the config alembic scripts.

* Added the CDR table alembic creation script.  The CDR table is more of
an example for new setups since the actual table can be fully customized
in cdr_adaptive_odbc.conf.
