[pve-devel] [PATCH ha-manager v3 01/13] rules: introduce plugin-specific canonicalize routines

[Daniel Kral]

These are needed by the resource affinity rule type in an upcoming
patch, which needs to make changes to the existing rule set to properly
synthesize inferred rules after the rule set is already made feasible.
