Public bug reported:

Currently the failures during the creation of resources related to the
creation of a HA router are handled my a try/except to avoid a potential
lock wait timeout. This has been done in order to keep the RPC calls
outside the transactions.

All the related resources are created in the _create_router_db but this
method is called inside a transaction which is started is the
create_router method. Moreover the try/except mechanism used to rollback
the router creation will not work since we are in a already opened
transaction.
