This story encompasses the move from openstack compute nodes to docker/kubernetes worker nodes. The changes involved renaming compute nodes to worker nodes, renaming VM functions to Application and making vswitch and nova-local optional.


Changed functionality:

Compute personality/subfunction renamed to 'worker'
CLI changes: host-add, host-bulk-add, host-update, host-show, host-list, dcmanager patch
Horizon Changes: Host Inventory, Host personality, edit host, host overview, patch orchestration, dcmanager patch
The pxeboot console has also been updated to use worker

CPU VM function renamed to 'Application'
CLI changes: host-cpu-*
Horizon changes: host processor

VM huge pages renamed to 'Application huge pages'
CLI changes: host-memory-*
Horizon changes: host memory, host update memory, force-host-lock


vswitch changes
* If vswitch_type is 'None'
  - newly installed worker hosts will start with 0 vswitch cpus
  - vswitch cpus can only be set to 0 through 'system host-cpu-modify' or platform horizon
  - vswitch cpus must be 0 when a worker node is unlocked

* If vswitch_type is 'ovs-dpdk'
  - newly installed worker hosts will start with 2 vswitch cpus (this behavior is unchanged)
  - vswitch cpus must be at least 1 when a worker node is unlocked


nova-local changes
* The nova-local volume group is now optional. It is only required if the worker node has the openstack-compute-node=enabled label present.


huge page changes
* vswitch huge pages will only be allocated if vswitch_type is not 'None'
