Description of problem:
When a HostControllerComponent resource is initialized by the plug-in container, the follow error is seen in the agent's log:

ERROR [ResourceContainer.invoker.daemon-1] (rhq.modules.plugins.jbossas7.BaseServerComponent)- Failed to validate base dir for {JBossAS7}JBossAS7 Host Controller [/home/loleary/workspace/Cases/00744811/test-env/jboss-eap-6.0.0.GA/domain].
java.lang.Exception: Failed to read attribute [domain-base-dir] of address [] - response: Result{outcome='failed', failureDescription=JBAS010850: No handler for operation read-attribute at address [
    ("host" => "master"),
    ("core-service" => "host-environment")
], rolledBack=true}

Version-Release number of selected component (if applicable):
4.4.0.JON311GA

How reproducible:
Always

Steps to Reproduce:
1.  Install EAP 6
2.  Change the master host name from `master` to `mymain`

        cd "${JBOSS_HOME}"
        sed -i 's/<host name="master" xmlns="urn:jboss:domain:1\.3">/<host name="mymain" xmlns="urn:jboss:domain:1.3">/' "domain/configuration/host.xml"
    
3.  Start EAP server in domain mode

        cd "${JBOSS_HOME}/bin"
        ./domain.sh
        
4.  Start ON system
5.  Import EAP host controller into ON inventory
  
Actual results:
Agent log contains the error mentioned above

Expected results:
No error in the agent log

Additional info:
This is because we assume that the EAP host controller is named "master." Not sure why we are doing this as the host controller's name is determined by the user at configuration time.

Specifically, we are using hard coded values ENVIRONMENT_ADDRESS and HOST_ADDRESS in HostControllerComponent[1] which are used in validateServerAttributes[2]
