Enhancement: Log component info

[carrolp]

Is your feature request related to a problem? Please describe.
When request-util logs are produced, it is not immediately obvious from where they originated -- e.g. "service X version Y produced this log". When problems are identified, it's not immediately obvious that the service is a very old version for example.

Describe the solution you'd like
When requestUtil logs are generated, include information about the component. Perhaps by loading a string from a well defined environment variable like REQUTIL_COMPONENT and (if available) including it in ReqUtil logs. Consuming components/services could set this env var to an appropriate name+version string.

Describe alternatives you've considered
