[pve-devel] [PATCH-SERIES container/ha-manager/manager/qemu-server v2 00/15] HA node affinity blockers (#1497)

[Daniel Kral]

Changes v1 -> v2 (Thanks @Fiona!):
 - rebase on master
 - fix initial node assignments in test case descriptions
 - make get_resource_motion_info(...) only read files once (introducing 3
   additional patches)

Tested changes with strict & non-strict HA node affinity rules and manual
migrations (in the CLI & web interface) as well as failback set and cleared.


This patch series implements node affinity rule migration blockers
similar to the blockers introduced with resource affinity rules.


The node affinity rule migraton blockers prevent users from migrating HA
resources to nodes, which would make them migrate somewhere else
immediately afterwards. This includes:

- online nodes, which are not part of the strict node affinity rule's
  allowed node set at all, or

- if the HA resource has failback set, online nodes, which are not in the
  currently highest priority group of the strict or non-strict node
  affinity rule.


The first few patches are some overall cleanup for things the series
touches + deduplicating the resource_motion_info logic and sharing it
between the Manager and the public
PVE::HA::Config::get_resource_motion_info(...), as well as exposing these
in the relevant VM/LXC API handlers and web interface.
