Fix cellsv2 cell0 database name

For some reason we were defaulting the name of the cell0 database
to nova_api_cell0 instead of nova_cell0. Devstack inherited that to
make things work, but we don't really want that. This patch makes us
use the proper name and create the cell0 mapping accordingly. As a
side effect, it also starts the process of unifying the cellsv1 and
cellsv2 paths by creating the cell0 mapping the same for both.
