Adds a new variable, 'disable_firewall', which defaults to true. If set
to false, then the host firewall will not be disabled during
kolla-ansible bootstrap-servers.

By default, Ansible injects a variable for every fact, prefixed with
ansible_. This can result in a large number of variables for each host,
which at scale can incur a performance penalty. Ansible provides a
configuration option [0] that can be set to False to prevent this
injection of facts. In this case, facts should be referenced via
ansible_facts.<fact>.
This change updates all references to Ansible facts within Kolla Ansible
from using individual fact variables to using the items in the
ansible_facts dictionary. This allows users to disable fact variable
injection in their Ansible configuration, which may provide some
performance improvement.
This change disables fact variable injection in the ansible
configuration used in CI, to catch any attempts to use the injected
variables.

Magnum has various sections in its configuration file for OpenStack
clients. When internal TLS is enabled, these may need a CA certificate
to be specified.
This change adds a CA certificate configuration, based on
openstack_cacert, for all clients using internal endpoints.
Note: we are explicitly not adding the configuration for the
[magnum_client] ca_file and [drivers] openstack_ca_file options, since
these use the public endpoint by default. These options may be
provided via custom configuration if necessary.

Kolla Ansible runs iscsid in the foreground (-f) and
a recent change to iscsid in CentOS 8 (both Linux and Stream)
caused it to reject setting pid file in such a case.
PID file is irrelevant in this scenario so this commit
removes its parameter.

This reverts commit c6259158e3eff4aff9770b7044b0179a7de533aa.
Reason for revert: cAdvisor fails with:
invalid value "percpu,referenced_memory,cpu_topology,resctrl,udp,advtcp,sched,hugetlb,memory_numa,tcp,process" for flag -disable_metrics: unsupported metric "referenced_memory" specified in disable_metrics

Follow up fix for Ia7e923dddb77ff6db3c9160af931354a2b305e8d, which
broke the cephadm jobs.

Adds support for passing extra runtime options to cAdvisor.
By default new options disable exporting rarely useful metrics
and labels by cAdvisor. This helps reducing the load on Prometheus
and cAdvisor itself.

They are handled by Docker since at least 18.09 (tested).
Backport to Wallaby at most to not introduce needless restarts in
already stable branches.
