Add a seperate controller subnode to subdivide the memory load
The number of required plugins has increased to the extent that
controller on Zuul FT infrastructure almost runs out of memory [1].
This potentially induces various problems such as FT failure noises
or POST_FAILURE at the ansible task 'export-devstack-journal'.
To request expanded images such as ubuntu-focal-expanded (16GB) or
ubuntu-focal-32GB would be an option, but it turns out that would
lead us to another problematic situation. [2]
This patch, instead, addresses the issue by subdividing the memory
load. As a first step, introduce a new subnode 'tacker-controller',
on which both tacker-server and tacker-conductor are located.
Note:
* when we re-locate some other components to this new subnode, it might
better to rename it.
* `devstack_local_conf: {}` in .zuul.yaml is to cancel out the global
job.vars devstack_local_conf.post-config.$NEUTRON_DHCP_CONF, which
is not present on 'tacker-controller' in the first place.
* TACKER_MODE is set to 'standalone'. 'all-in-one' supposes core
services like nova, neutron, keystone, etc. api servers are located
on the same host as tacker-server.
* in devstack/lib/tacker:create_tacker_accounts, SERVICE_HOST should
have been TACKER_HOST. this minor fix is included.
* in roles/setup-default-vim/tasks/main.yaml, the same where conditions
were scattered but all tasks in it just needed to run on 'controller'
only. so let us wrap them all in a block.
* renamed devstack/plugin.sh:tacker_register_default_vim for clarity.
* policy file modification for Heat is now done by an ansible task.
it frees us from the co-location requirements for Tacker and Heat.
* drop devstack/lib/tacker:is_tacker_enabled as it's no longer needed.
[1]: we investigated how severe the memory load on 'controller' was
on Zuul FT infrastructure:
* The highest memory-consuming processes in desc order:
