[BZ 1128929] One more revision to clarify that the encode utility can now be used for configuration values in general (not just passwords). Updated the name of the utilities, prompts, and command arguments to activate the feature.
Bug 999494 - Import child Resource: jboss as (both eap 4 and 5) are not being imported to inventory list after successful import operation

Not only tell the user a request has been submitted, but if the request failed or succeed and why.

So now the user knows if nothing happens because the resource in already in the inventory, in the discovery queue, or ignored.

[1071282] disk size used by storage metric is invisible when no metric is collected
[1071291] no-data-available metric values for storage node metrics

The --no-data-available-- is our standard text formatting when a Double is
either null or NaN (using MeasumenentConvertClient).  So I couldn't just change
that across the board.  But in this instance I agree the table looked
odd and inconsistent.  So, now using "NaN" in this scenario.  As for the
missing metric entry, certain metrics are simply not able to be reported
immediately.  For the one in question I made sure it is there, if possible,
with "NaN" values.

But understand that it is possible to actually get no metrics for a very
brief period after import. Also, it is possible the metric set may lack a
metroc or two for a brief period.  The fix covers things as best as
possible. Remember that this entire issue goes away very quickly, as soon
as metrics are initially reported.

Probably more important than the BZ changes were some fixes I found along
the way:
- limit the StorageNode.QUERY_FIND_UNACKED_ALERTS_COUNTS query to committed
  storage node resources, otherwise it can report incorrectly. (sorry for the
  file reformat)
- Fix the AVAILABILITY column handling, use our more common approach to
  avoid some issues. It was working a bit by luck.
- Fix the STATUS field record value, it should be a string.
- Change some formatting to allow more space both for the metrics table
  as a whole (in the detail view) and also the metric name column.
- Fix clusterStatusItem value, it should be a String.
- Fix messageItem value, it should be a String.
- Protect against a potential bad widget ID
- Apply CellFormatters prior to setting ListGridFields, and Fix == to be
  equals() to ensure proper CellFormatter is applied

[BZ 1129910] Fix CL leak in agent plugin & AgentManagement MBean

The AgentManagement MBean is running inside the agent JVM.

When a restart operation of sorts is invoked from within the RHQ
Agent plugin (as its operation), the invocation on the MBean (done
through EMS) inherits the protection domain of the plugin classloader.

But the result of the operation is a new start of the plugin
container (eventually) which will create a whole lot of new
classloaders, all of which will inherit the protection domain and
access control context of the original RHQ agent plugin classloader.
The protection domain holds a reference to the classloader it is
associated with.

As a result all the all the classloaders in the new "incarnation" of
the plugin container will hold a reference to the original plugin
classloader of the agent plugin. This will cause the classes from
that agent plugin to never unload.

Rinse and repeat and you start to get OOMEs and full permgen.
