[Feature Request] Snapshot restore should allow renaming aliases #15632
Description
Is your feature request related to a problem? Please describe
Snapshot restore takes a pair of arguments to allow renaming indexes into new names. The common example use case to restore snapshots into the same cluster as temporary separate indexes for research and debugging. However, this is problematic if this indexes has aliases to be restored. I am not sure if the indexes will be linked to the existing aliases or this is an error, but either case would problematic, since this either breaks desired isolation or fails.
Describe the solution you'd like
Snapshot restore should take a new pair of arguments to allow renaming aliases into new names to match the existing pair of arguments for index renaming. For backend compatibility, these arguments should be optional.

Describe alternatives you've considered
In some cases, it may be possible to restore any necessary aliases after the snapshot restore is completed. It is also possible to restore into another cluster. The drawbacks of these two options is obvious, however.
