Review comment:
       I actually tried this initially but found the result to be a lot like 
the code in `CollectionsApiMapping.Meta`, which I personally find tough to read 
with all the map-literals for renaming properties and prefixing properties.  I 
guessed it was more readable to just call this non-recursive version twice.  
That wouldn't work as well on APIs with deeper nesting, but seemed feasible 
here.
   
   I'm open to going back that direction though if you prefer it.  Did you have 
a particular signature in mind?

Review comment:
       They should definitely exist somewhere, but they're not 
`/v2/collections` APIs, so I didn't do that in this PR.  If you guys really 
want them, I'm not against adding those constants in this PR.
   
   But even then they should probably live somewhere else, shouldn't they? 
(since this class is for `/v2/collections` APIs, and those commands are for 
other APIs?  AFAIK this file is only for those APIs that specifically live 
under `/v2/collections`, right?)

Review comment:
       Good catch.  There's a Jackson annotation made for this case 
(`JsonAnyGetter`) - named properties will be mapped as usual but "extra" ones 
are put in a Map or whatever.  But it looks like we're not actually using 
Jackson here to avoid SolrJ needing to depend on Jackson.
   
   I could create clone JsonAnyGetter the way we've done with JsonProperty, but 
idt it's worth it.  I'll just remove this RouterInfo class and handle all the 
properties as a Map for the translation.
   
   Might be worth considering whether a Jackson-dep is worth it after all going 
forward though.

(`JsonAnyGetter`) - named properties will be mapped as usual but "extra" ones 
are put in the catchall Map.  But it looks like we're not actually using 
Jackson here to avoid SolrJ needing to depend on it.  The JsonProperty 
annotation is a copy  in our own code to avoid the dep.
