Description of problem:
When attempting to execute the discovery --resourceType=<resource> command, the command syntax is not properly parsed when the long form is used with a argument that contains a space (such as a resourceType).

For example:

    discovery --resourceType="JBossAS Server"

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

How reproducible:
Always

Steps to Reproduce:
1. Install the JBoss AS and AS5 plug-ins
2. From the agent prompt command, execute:

       discovery --resourceType="JBossAS Server"

 
Actual results:
Command fails and the agent simply spits out:

    Syntax: discovery [--plugin=<plugin name>] [--resourceType=<type name>]
                      [--resourceId=<id>] [--verbose]
            discovery --full [--verbose]
            discovery --blacklist={list|clear}


Expected results:
Command should succeed and the following should be output:

    JBossAS.JBossAS Server: Starting discovery...
    JBossAS.JBossAS Server: Process scan detected a server - scan=[ProcessScan: query=[process|basename|match=^java.*,arg|org.jboss.Main|match=.*], name=[JBoss4]], process=[process: pid=[25545], name=[/etc/alternatives/java_sdk/bin/java], ppid=[25535]]
    JBossAS.JBossAS Server: key=[/home/loleary/workspace/Cases/00750460/test-env/jon-server/jbossas/server/default], name=[loleary:2099 RHQ Server], version=[AS 4.2.3.GA], description=[JBoss Application Server 4 hosting the RHQ Server]
    JBossAS.JBossAS Server: Done.

    JBossAS5.JBossAS Server: Starting discovery...
    JBossAS5.JBossAS Server: Process scan detected a server - scan=[ProcessScan: query=[process|basename|match=^java.*,arg|org.jboss.Main|match=.*], name=[jbossas]], process=[process: pid=[25545], name=[/etc/alternatives/java_sdk/bin/java], ppid=[25535]]
    JBossAS5.JBossAS Server: Done.


Additional info:
To get this command to successfully execute, the equal sign (=) can be removed from the argument assignment. Please note that although this works, it is not the expected behavior considering the command syntax is resourceType=<resource_type>

    discovery --resourceType "JBossAS Server"

Equally, the short form of the command also works:

    discovery -r "JBossAS Server"
