Mount hostpath logs on /var/log

Mount hostpath logs on /var/log

Some containers are using the logs named volume for collecting logs
written to `/var/log`. We should make this consistent for all the
containers.

This patch also cleans up some mounts that weren't needed for some
services. For example, glance-api doesn't need `/run` to be mounted.

Other changes:
* Rework log volumes to hostpath mounts to omit slow COW writes.
* Add kolla_config's permission and host_prep_tasks create and
  manage hostpath mounted log dirs permissions.
* Rework data owning init containers to kolla_config permissions
* When a step wants KOLLA_BOOTSTRAP or DB sync, use logs data owning
  init containers to set permissions for logs. This is required
  because kolla bootsrap and DB sync runs before the kolla config
  stage and there is yet permissions set for logs.
* In order to address hybrid cases for host services vs containerized
  ones to access logs having different UIDs, persist containerized
  services' logs into separate directories (an upgrade impact)
* Ensure host prep tasks to create /var/log/containers/ and /var/lib/
  sub-directories for services
* Fix missing /etc/httpd, /var/www config-data mounts for zaqar/ironic
* Fix YAML indentation and drop strings quotation.
