Description of problem:
If the apply-updates command is used against a JBoss ON server that has not yet been installed or for one that is standalone--without a storage node--the rhqctl install command will fail and rhqctl start will report startup errors for rhq-storage.

Version-Release number of selected component (if applicable):
3.3.1

How reproducible:
Always

Steps to Reproduce:
1. Extract jon-server-3.3.0.GA.zip to /opt/jboss/on
2. Apply update-01:

       /tmp/jon-server-3.3.0.GA-update-01/apply-updates.sh /opt/jboss/on/jon-server-3.3.0.GA

3. Run the server installer:

       /opt/jboss/on/jon-server-3.3.0.GA/bin/rhqctl install

Actual results:
Install is not performed and the following is displayed:

    21:06:17,366 INFO  [org.jboss.modules] JBoss Modules version 1.3.3.Final-redhat-1
    21:06:17,558 INFO  [org.rhq.server.control.command.Install] The RHQ storage node is already installed in [/opt/jboss/on/jon-server-3.3.0.GA/rhq-storage]. It will not be installed.
    You must set the CASSANDRA_CONF and CLASSPATH vars
    21:06:17,568 INFO  [org.rhq.server.control.command.Install] Pausing to ensure RHQ Storage is initialized prior to RHQ Server installation.


Expected results:
Install is performed as normal with no "You must set the CASSANDRA_CONF and CLASSPATH vars" error.

Additional info:
This is because 3.3.1 contains a new <RHQ_SERVER_HOME>/rhq-storage/bin/cassandra file. This file causes the rhq-storage directory to be created making the rhqctl command think that an rhq-stroage node is installed. 

The apply-updates command needs to only place files in rhq-storage in the even that the directory already exists. If the directory does not exist, any new/backup/deletion of files with the path ./rhq-storage should be skipped.
