* Revert "Require DATASOURCE WRITE access in SupervisorResourceFilter and TaskResourceFilter (#11680)"
This reverts commit 6779c4652d.
* Fix docs for the reverted commits
* Fix and restore deleted tests

Follow up PR for #11680
Description
Supervisor and Task APIs are related to ingestion and must always require Datasource WRITE
authorization even if they are purely informative.
Changes
Check Datasource WRITE in SystemSchema for tables "supervisors" and "tasks"
Check Datasource WRITE for APIs /supervisor/history and /supervisor/{id}/history
Check Datasource for all Indexing Task APIs

* Add paramter to loadstatus API to compute underdeplication against cluster view
This change adds a query parameter `computeUsingClusterView` to loadstatus apis
that if specified have the coordinator compute undereplication for segments based
on the number of services available within cluster that the segment can be replicated
on, instead of the configured replication count configured in load rule. A default
load rule is created in all clusters that specified that all segments should be
replicated 2 times. As replicas are forced to be on separate nodes in the cluster,
this causes the loadstatus api to report that there are under-replicated segments
when there is only 1 data server in the cluster. In this case, calling loadstatus
api without this new query parameter will always result in a response indicating
under-replication of segments
