flat network type is not mandatory. There are two cases,

1. ironic with flat network: we can use neutron vlan network to
   provision baremetal nodes, as long as the interface of the baremetal
   nodes are configured to use the same vlan.

2. ironic with neutron network: all provision and cleaning_network can
   be vlan type and no flat is needed at all.

So we should remove the task.

This allows for skipping tasks which match the provided tags, using
the ansible-playbook argument of the same name.

This can be useful in combination with --tags, to skip reconfiguration
of the common tasks:

kolla-ansible reconfigure --tags nova --skip-tags common

kolla-ansible can take globals.yml from any directory by using
--config-dir argument. So store admin credentials there as well.

Not everyone runs kolla-ansible as a root.
