      Description

      SOLR-13262 changed the behavior of most collection admin commands so that they always resolve aliases by default. In most cases this is desireable behavior but it also prevents executing commands on the collections that have the same name as an existing alias (which usually points to a different collection).

      This behavior also breaks the REINDEXCOLLECTION command with removeSource=true, which can also lead to data loss.

      This issue can be resolved by adding either an opt-in or opt-out flag to the collection admin commands that specifies whether the command should attempt resolving the provided name as an alias first. From the point of view of ease of use this could be an opt-out option, from the point of view of data safety this could be an opt-in option.
