On OSP17 there are some ml2 ovs services that are not
present on some computes eventhought is defined on the
ansible service facts.
This patch will ensure that only those services that are
actually running will be stopped.
Change-Id: I94f0832d09d263837262ada109a567e864915a1a
Before this patch, when migrating from ML2/OVS to ML2/OVN, we
removed the VIF details that are not used by OVN. However, this
changes how the VIFs are plugged if the hybrid iptables firewall
was used.
In order to not break the migration, we want to keep whatever
plugging was used in ML2/OVS. For this reason, this patch is
leaving the VIF details untouched.
The consequence is that, after migration, whatever workloads
used the hybrid plugging will remain like that. Newly created
VIFs will be plugged to the OVS bridge directly. As a result,
the migration to OVN won't require moving to the OVS firewall
first while in ML2/OVS.
This patch is also removing the constraint that prevented the
migration if the hybrid firewall was used.

[1] Updated the migration script to check for config-download
directory instead of stack, but missed update the Error
message.
check_stack function is renamed to check_source_inventory
as now it only checks for source inventory instead of heat
stack.
If source inventory file doesn't exist the script
will report Error message and exit.
This is follow up of [1].

The validation is intended mostly for tests and don't make much sense
when running the migration in production because likely there are
already running workloads. This patch changes the default to False so
migration validation must be explicitly asked for.

tripleo-ansible-inventory stopped working in Wallaby. However, TripleO
now stores the needed ansible-inventory on the undercloud filesystem.
This patch switches from dynamic generation of the Ansible inventory to
use of the already existing inventory file. Fortunately, the format of
the file remained the same as the generated one, so no other changes in
parsing are required.

It's a common practice to have /tmp/ mounted separately with noexec
option. This effectively means no scripts can be executed from the
filesystem mounted to /tmp.
This patch explicitly calls sh binary to execute scripts from /tmp and
removes the executable flag from the scripts.

During the clone-br-int the interfaces sg- (SNAT)
and the interfaces fg- (FIP) are cloned. But this
is not necessary, since this kind of interfaces
are useless on OVN (OVN uses OpenFlow).

Port status, server status and server console log output are printed
when the create-resources.sh script fails during the OVN migration
Example: OVN migration fails because SSH connection is not possible,
after ping successfully replied - probably a metadata issue and having
the console logs could help to identify it

After stopping and deleting the services if this role is runned
again it could fail bc systemd has still some ovs services loaded
(eventhough the service is stopped) this will cause that ansible
will try to delete again and fail while trying to disable and
delete the service.

Following fixes are done in the script:-
- Use openstack_citest as db user as done in CI[1] as
with root as db user it fails configure it.
- Use MYSQL_USER var instead of hardcoded root user
- Fix Syntax Error in CREATE USER psql command by using
quotes for DATABASE_PASSWORD
- Swith to root user for running psql command as without
it, it asks for stack user password which is not configured,
same is done in devstack[2].
- Create variable DATABASE_NAME for database name and use
at all required places.

While migrating from OVS to OVN one of the steps of the migration
is clean all the OVS trunk ports, this will fail if the environment
does not have any trunk ports configured.
This will do a comprovation in order to know if it's necessary
to clean them or not.
Also, since this playbook it will only clean the ovn interfaces
it is not necessary to stop the whole migration. If any error
occured while deleting any ovs interface a message will be
printed so the user can take action if necessary.

This is basically revert of the [1] which was revert of the [2]
but now it should not break our CI jobs.
In the configure_for_func_testing script openvswitch is installed
from source. We need to set proper flag (Q_BUILD_OVS_FROM_GIT) which
is used in Devstack to tell Devstack to install it from source and
not from packages.
This patch also removes flag BUILD_OVS_FROM_SOURCE from the
configure_for_func_testing file as it was only used in that file
and was actually duplicating the Q_BUILD_OVS_FROM_GIT option used also
in Devstack.

Reason for revert: This patch is breaking CI testing, functional jobs. Variable

From a now broken CI job:

It's not needed at all so if we avoid installation, especially from
sources, it may save us few minutes of the job's execution time.
It may also save some resources on the node.
To save a bit more time in the fullstack job's execution this patch also
disables compilation of the OVS from source in that job. We can use OVS
installed from packages provided by the distro instead.

This patch adds definition of the functional and fullstack jobs
with enabled support for FIPS [1].
Jobs are based on the Centos 8 stream as this disto allows to enable
FIPS support.
Jobs are added to the experimental queue for now.
This patch also makes some changes in the bindep and
configure_functional_tests role to make functional/fullstack tests
working on the Centos.
