... module/git, unit/dynamic, unit/static
New `module/mongo'
New `module/softlayer'

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
Updated `travis'

Moved some package installs into the specific module requiring it in
order to reduce the shared build commands, thus speeding up all
builds as a result.
Updated `module/remote': ldap dependency removed

This module no longer (directly at least) depends on the ldap module.
