Updated `util': encapsulated `jsontool'
... module/git and lib/libsh/libsite/unit/dynamic.csv
New `mongo': mongodb module
New `softlayer': softlayer module

New site module that interfaces with `extern/softlayer'.
Updated `libexec/softlayer': flag for cache added

Added a programatic flag (variable) to enable/disable caching, and
set that to false as softlayer API calls are not too costly.
New `module/pagerduty': pagerduty module
