#4459 [HHQ-4326] Add servlet session manager metrics to WebSphere

[Hyperic Team]

http://jira.hyperic.com/browse/HHQ-4326
Currently we're unable to collect session metrics. WAS admin console(shot-4) is showing metrics under "Servlet Session Manager" but from jmx point of view those are mapped to application/war files. This pretty much equals the "Webapp" what we have under WebSphere resource in HQ.

I made a simple test to add these metrics under Webapp and it took only 30 minutes. You'll see the result from shot1-shot3. Modifications to source code were pretty minimal. There's patch file attached against HQ_4_4_0_GA tag.

We could create a new "Servlet Session Manager" service under WebSphere server resource and map these services there but that may not be necessary. Anyway session are always related to deployed webapps and that might just be the logical place for these metrics.

This was only tested against WAS6.1 fix pack 31 on windows.
