SOLR-17877: Introduce cluster property overseerEnabled, replacing dual booleans
(#3524)
The SolrCloud Overseer is disable-able, in lieu of a simpler distributed mode of
cluster command and collection state processing. In Solr 9 this was possible
with undocumented
/ unsupported configuration in solr.xml (`distributedClusterStateUpdates` &
`distributedCollectionConfigSetExecution`). Those are now removed. In their
place is a new
overseerEnabled cluster property and an env var SOLR_CLOUD_OVERSEER_ENABLED.
> Create overseerEnabled cluster property

> Project: Solr
> Issue Type: Improvement

> Create an "overseerEnabled" cluster property.
> The "distributedClusterStateUpdates" and
> "distributedCollectionConfigSetExecution" in solr.xml cloudConfig shall be
> removed, and instead both behaviors togged with a single boolean setting
> relating to overseer enablement. They weren't documented / advertised.
> If the new cluster property isn't set, we can examine the EnvUtil
> "solr.cloud.overseer.enabled" secondarily. In _another issue_ in Solr 10, a
> third evaluation is done to consider the least Solr version of Solr nodes.
