Review comment:
       nah, I actually meant maxLength here (because kubernetes resource names 
cannot go beyond 63 characters: 
https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#dns-label-names)
   
   Good find!

Review comment:
       So this is just a name for the backup repository, it is pretty 
independent from the name of the SolrCloud (which has limitations given by 
Kubernetes, which I linked below).
   I used the same regex, but changed it to allow capital letters and 
underscores, since we don't need to be as strict with the names of the 
repositories (as far as I know).
   
   Is there any limitation in Solr for the name of backup repositories? If so 
we should definitely change this to match.

Review comment:
       So yeah, just to be very clear, I'm just following the guidelines for 
[kubernetes resource 
names](https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#dns-label-names).
 This field is a reference to SolrCloud resources, so there is no way that 
giving a string that has a length > 63, or doesn't match that regex, is going 
to be successful (because we will never be able to find a SolrCloud in 
kubernetes with the given name).
