[openstack-dev] [neutron] VxLAN UDP port configuration

Hi everyone,

this is actually a follow-up from this previous thread and bug:

The OVS agent supports the "vxlan_udp_port" parameter in its
configuration file (for Linux Bridge there is an open bug, default
port is still used). But there is also a 'udp_port' column in
'ml2_vxlan_endpoints' table, that is currently not used.

Before merging https://review.openstack.org/#/c/153891/25 (feedback
welcome) that would actually update this table, should we keep specifc
per-host port configuration? There was a loose agreement in the
previous thread about going on with it, but using a common value
everywhere is a good alternative.
Most configurations would use the default port (either IANA or Linux),
and can be set to another port if needed. But per-host configuration
helps in mixed OVS/Linux Bridge setups.

Thoughts? To see if we keep on with this code or just drop the column
from database
