      .The Instance HA service supports a new parameter
      This enhancement adds the `TAGGED_AGGREGATES` parameter to the RHOSO high availability for Compute instances (Instance HA) service. By default, this parameter is set to `true`, so that the Instance HA service checks for tagged host aggregates. If you set this parameter to `false` then the Instance HA service does not check for tagged host aggregates and therefore will evacuate all the eligible Compute nodes.

      Goal: 

      we should expand the doc with a brief explanation regarding the new parameter TAGGED_AGGREGATES (true by default) and warn users that they should set it to false if they want to evacuate all their computes instead.
