The canonical path is the unique ID. it has the feed ID encoded in it so no 
need to call server for that.

Also, there is a new REST endpoint:

/hawkular/inventory/path/{canonicalPath}

to which you can directly pass the canonical IDs as part of the URL to 
retrieve the info about any type of entity. No need to extract the environment 
or feed id from the canonical path and then construct the "traditional" REST 
URL from it.
