> 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.
