Use <project>_install_type instead of kolla_install_type
to set python_path. For example, general kolla_install_type
is 'binary', but user wants to deploy Horizon from 'source'.
Horizon templates still use python_path=/usr/share/openstack-dashboard,
it is wrong.

Having all services in one giant haproxy file makes altering
configuration for a service both painful and dangerous. Each service
should be configured with a simple set of variables and rendered with a
single unified template.

Available are two new templates:

* haproxy_single_service_listen.cfg.j2: close to the original style, but
only one service per file
* haproxy_single_service_split.cfg.j2: using the newer haproxy syntax
for separated frontend and backend

For now the default will be the single listen block, for ease of
transition.

This commit is the final commit to apply resource-constraints
to all OpenStack services.

Depends-on: I39004f54281f97d53dfa4b1dbcf248650ad6f186
Change-Id: I072d69be9698be54775cb0ae286ea2b6ed78776c
Implements: blueprint resource-constraints

This change allows the following use cases:

1. Using an already-configured MariaDB / MySQL server / Cluster
2. Using already-created DB users, without requiring root DB access.

Update: added external mariadb precheck

Change-Id: I78b0d178306d7c5293b0bf53e445f19f18b4b824
Implements: blueprint external-mariadb-support.
Closes-Bug: #1603121

through the database_address has beed defined in groups_vars/all.yml, we should
better use it, this way, if we want to use external database, we just need to
redefined in all.yml
