stats monkey integration

[wimpers]

Stats monkey has (finally) been integrated in the framework
Its configurable through the Administration tab --> support page

When enabling the statsmonkey, credentials and some other information is asked, which is required to know how/where the stats should be stored

It is possible to configure the interval of each separate 'get_stats' method. To do so you need to add a key in /ovs/framework/monitoring/stats_monkey like so:
'get_stats_mds': 20 (in seconds)
This will cause the MDS stats to be collected every 20 seconds instead of the default of 60 seconds

For other possible keys you need to browse the code, cause you need the method name as key
