Way to set JNDI properties for twiddle
--------------------------------------

                 Key: JBAS-3637
                 URL: http://jira.jboss.com/jira/browse/JBAS-3637
             Project: JBoss Application Server
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
            Reporter: Owen Taylor
            Priority: Minor


It is frequently useful to be able to set JDNI properties when running twiddle - for example,
you might want to set jnp.disableDiscovery when checking the status of a particular server
that might not be running.

Right now, this is difficult to do. You can export a JBOSS_CLASSPATH
which contains a jndi.properties file before running twiddle.sh, but then you have to
include all the standard jars in it, which is quite annoying.

A pssible fixes would be one of:

 A) A way to prepend elements to JBOSS_CLASSPATH without disabling the default
  construction (also useful for getting a log4j.properties that doesn't drop twiddle.log
  in the cwd, perhaps)
 
 B) A command line option for specifying a particular properties file to load and pass
  to 'new InitialContext()' (slightly more convenient than A)

 C) A command line option to define particular properties:

    twiddle.sh -jnpProperty=jnp.disableDiscovery=true

  (Or some better syntax)

The twiddle code actually does:

         Properties props = new Properties(System.getProperties());
         props.put(Context.PROVIDER_URL, serverURL);
         ctx = new InitialContext(props);

In the case where a server URL is set, so there may have been intention that twiddle.sh -Djnp.disableDiscovery=true
would work, but AFAIK property inheritance doesn't work in that place - only the properties directly in props take 
effect, and system properties won't be looked at in the other code path either.
