The new master branch should point now to rocky. So, HOT templates should specify that they might contain features for rocky release [1] Also, this submission updates the yaml validation to use only latest heat_version alias. There are cases in which we will need to set the version for specific templates i.e. mixed versions, so there is added a variable to assign specific templates to specific heat_version aliases, avoiding the introductions of error by bulk replacing the the old version in new releases.

This is the minimum number of entries to keep in the ARP

fewer than this number of entries in the cache.

This is the soft maximum number of entries to keep in the

be performed.
