Deleting this class.

Technically this class was public, but no public plugin had ever refered
to it, and it's unlikely that anyone has referenced it, so this should
be safe.

Reduce PermGen pressure

Full clean Maven build has been failing with PermGen out of space on my system for

instances lying around, so create fresh ones each time to avoid this.

With this change, I no longer need bigger heap size.

[FIXED JENKINS-15869] When running on Java 5, must still load DiskSpaceMonitor/TemporarySpaceMonitor, even though they will show N/A.
Returning null from an @Extension method does not seem to work reliably, and is not supported by SezPoz.
If desirable to hide a monitor column in $server/computer/, add a boolean isEnabled() method interpretable in Jelly.
