collection properties

[Hendrik Haddorp]

Hi,

with Solr 7.3 it is possible to set arbitrary collection properties 
using 
https://lucene.apache.org/solr/guide/7_3/collections-api.html#collectionprop
But how do I read out the properties again? So far I could not find a 
REST call that would return the properties. I do see my property in the 
ZK file collectionprops.json below my collection though.

thanks,
Hendrik
