ae78e812d1 ovn-migration: Introduce migrate mode to DB sync tool
The new "migrate" mode for the DB sync utility changes DB contents as
follows:

 - it changes vxlan networks to Geneve, including its allocation in
   order to avoid future collisions when creating new geneve networks
 - it removes settings from ports' vif_details that are no longer
   needed, such as hybrid plugging or bridge_name for the trunk bridges
 - it sets profile for subports - OVN doesn't use trunk_details but port
   profile to store data about trunk. Subports have tag and parent_name
   fileds.

Previously, the vxlan to Geneve change was done via ansible role. The
tasks in the role were replaced by the script therefore the role is
removed.

94bea77fd7 migration: Remove crudini when migrating tunnels
It turned out there doesn't need to be crudini tool present on the node
running the command. This patch fetches the Neutron conf file instead
and performs an ini lookup over it in order to get the DB connection
string.

The Ansible command itself is hard to read, the patch adds some doctext
to improve understanding of the ansible task.

569aa4452a ovn-migration: Use DHCP nodes to configure dnsmasq
Previously, the migration script used controller nodes to configure
dnsmasq when configuring new MTU. Controller nodes may not run DHCP
agents. The patch detects DHCP agents instead and uses those to
configure dnsmasq.

d3fce77ff5 ovn-migration: Change network type from vxlan to Geneve
The patch goes to one of ovn-dbs nodes and runs a SQL query to change
all vxlan networks to Geneve. It's done via Python and sqlalchemy in
neutron_api container because mysql client is not installed there. This
approach was chosen to avoid installing more dependencies.

526693ed3c Remove ML2OVS-specific templates before migration to OVN
When running migration from ML2OVS to ML2OVN using infrared plugin
some ML2OVS-specific templates remain in 'overcloud deploy' command.
This is not correct and can cause issues.

4b30dc2330 ovn migration: Fix neutron server container name
Previously docker command used grep to search for neutron server
container. It used image name instead of container name. With the switch
to podman, it stopped working. This patch fixes the container name.

4ad21fd23a migration: Restart OVS after setting protocols
This patch is a workaround for bug in OVS [1]. The OVS is restarted
after setting protocols for the integration bridge. This will cause
a data plane disruption. We can remove the workaround once
the bug [1] is fixed.

TripleO used to uninstall services if the resources were set to None. It
was not intentional and TripleO no longer does that. This patch manually
removes dhcp, l3, metadata and ovs agents from controller and compute
nodes, including its systemd service files.
