Description of problem:

Currently our REST API allows creating a resource, but there is no way to pass configuration for such resource. If I try to create such resource (i.e. Network Interface on AS7 Server) it get's created, but does not appear in Child History and it's kind of broken (configuration fails to be loaded, I am not able to delete such resource)

Version-Release number of selected component (if applicable):
RHQ 4.7-master

How reproducible: always


Steps to Reproduce:
1. have RHQ with imported AS7 Standalone server (ID 123456)
2. run 
curl -v --data "{\"resourceName\":\"testnetifaceX\",\"typeName\":\"Network Interface\",\"pluginName\":\"JBossAS7\",\"parentId\":123456}" -H "Content-Type: application/json" -H "Accept: application/json" --anyauth -u rhqadmin:rhqadmin http://127.0.0.1:7080/rest/resource

  
Actual results:

REST API returns new resource, resource is created in inventory. This creation does not appear to history.

When I open Inventory tab of this new resource, UI reports 

The following connection settings have invalid values: [Path]. The values must be corrected before the settings can be saved.

I am not able to delete such resource with error:

java.lang.IllegalArgumentException: Delete for [null] failed: JBAS014739: No handler for remove at address [], rolled-back=true
	at org.rhq.modules.plugins.jbossas7.BaseComponent.deleteResource(BaseComponent.java:333)

Expected results:
