Review Comment:
Not sure if these methods belong here but it is required to convert the
initial set of String urls into cluster state node names

Review Comment:
> I think the idea of this JIRA issue is that we'll take the Solr URLs as
configured and use this is the initial / backup liveNodes. I think this is a
very simple idea to to document/understand/implement.
That makes sense. This leaves me with a few questions then. Shouldn't this
take a list of `URL` or `URI` java object to verify actual non malformed URLs
instead of a list of URLs? I created the functions below to convert these
Strings into cluster state nodeNames for `liveNodes`
