[Clas12_software] update

[Vardan Gyurjyan]

This is not a critical update, and is relevant to monitoring.

Release notes:
- added pool size reporting for a service. This is an actual core count participating in the processing: Sebastian Mancilla
- fixed bug in the Clara installer, reported by Markov N. This will prevent dangling/leftover processes.

Actions:

1) stop or wait until clara reconstruction processes are done.

2) kill dangling Clara processing sessions:

> ps -ef | grep java 
will indicate process id’s.
> kill -9 <procesID>

3) update clara installation
> install-claracre-clas -u

P.S. at the moment I can see two dangling processes: 
1) user=celentan on the node=129.57.70.18
2) user=davita on the node=129.57.70.15
