Bug 801153

The basic issue we're trying to overcome is the following:
"I started my EAP instance, why isn't it showing up in JON?"

The underlying issue is that server discovery scans only happen every 15mins by default (and service scans every 24hrs).

We need to consider options for how to make it more apparent to users what's going on, i.e. discovery hasn't run since you turned on the AS instance.

Possible options
-Fire process level discovery much more frequently. Not sure how this is achievable while maintaining low CPU utilization. Perhaps we could have the plugins register metadata with the PC, and the PC could then do a single process scan for all plugins, and only actually call a given plugin if it finds new candidate processes. Basically make the PC more event driven.
-Let the user know when the next discovery is scheduled for a platform. This would help indicate to the user why a server may not have been discovered yet.
-"Discover now" button, on a platform or a server 
-New Discovery Queue layout
--List of all platforms, include a column for next discovery time 
--Sort rows by number of child servers ready to be imported, so the platforms with actionable items are at the top
--Make available, but not as the default, a filter on platforms which would exclude platforms with no child servers to import, i.e. hide stuff you don't care about. Its not enabled by default because then you are back to the same situation as you have today.
