Resource summary file on BU

[smorovic]

We have already switched to using resource_summary file.

Current version contains
"activeRunCMSSWMaxLS" - integer, initial value: -1
(this will show max LS seen by any CMSSW once initialized, needs version >=7_3_2_patch5)

hltd 1.7 will add:
"stale_resources - integer, default value: 0

• this will be 0 unless we detetect lag or problems with updating files on ramdisk via data network (assuming box files are updated through control network).
  In case of problems, resources will be counted here instead as active_resources and those that are acounted in it: idle,used,broken). "cloud" resources are never counted as stale.
