Make fields for password injection configurable

Nova can inject root passwords into instances. Not all hypervisors support
that feature and visibility of the password fileds can get configured.

The relevant patch is not upstreamable, so this is only effective when
the dashboard package from the openSUSE build service is used.

Configure nova_dashboard to not disply the password fields.

Make the can_set_mount_point hypervisor option configurable

As the mount point can only be set with Xen, many people might not want
to have the field for this visible. So we add an option for this, which
defaults to False.

Note that there's no schema migration since the new attribute is
optional.

Always store port list as strings

for some reason the ceph barclamp injects the port numbers
as strings, so in order to not have the uniq sorting fail,
we need to convert everything to strings.
