The default value of default_boot_option configuration will
change eventually from "netboot" to "local".
It is recommended to set an explicit value for it during the
transition period

If we don't use cirros image, ``image_ssh_user = cirros`` is wrong,
so we should make it be variable.

Normally chronyd will cause the system to gradually correct any time offset, by slowing down or speeding up the clock as required.
In certain situations, the system clock might be so far adrift
that this slewing process would take a very long time to correct the system clock

gnocchi have archive policy rule feature, which can control metric's
archive_policy. gnocchi also have a default archive policy rule which
is using low archive policy.

On the other hand, archive_policy is marked as deprecated and will be
removed in the feature in ceilometer[0].

So should better remove archive_policy ceilometer.conf.

This patches changes deploy_gate quite a bit so in reality all
deployments will now assume multinode (even if it's single node). After
that we will refactor it even further to enable easy addition of new
scenerios.

Actually Openstack services configuration can be overriden using many
files:
- /etc/kolla/config/<< service name >>/<< config file >>
- /etc/kolla/config/<< service name >>/<<host>>/<< config file >>
- /etc/kolla/config/global.conf
- /etc/kolla/config/database.conf
- /etc/kolla/config/messaging.conf

Only per-service configuration is actually documented here:
https://github.com/openstack/kolla-ansible/blob/master/doc/advanced-configuration.rst#L164

Allowing to globally modify service configuration can be perform too,
but it can be done in 3 different manners:
- /etc/kolla/config/global.conf
- /etc/kolla/config/database.conf
- /etc/kolla/config/messaging.conf

database.conf and messaging.conf seems redundant with global.conf.
In order to simplify codebase it seems logical to deprecate them.

In case Kolla's users want to deploy with both of
binary and source image, we should have a variable
install type that define install type for each project.

We also add specific image tag for each Openstack project.

This commit is implemented for Neutron, Nova,
Octavia project and Openvswitch as well.
