Use the example provided in the Ruby Client to provide a customised
collector appropriate to log all calls to the API. The customised
filtering is used to replace individual node names and templates
for the /vm and request ID's for the /ondemand endpoints.
This module was failing our rubocop checks so have updated it since
it now forms part of vmpooler.
Separate trapping for litmus jobs is also included so that they don't
interfere with stats from the jenkins pipelines.
