Implement Prometheus Collector pattern

[natiiix]

This PR changes the Prometheus metrics registry/server used by IO from the legacyregistry to an HTTP registry served directly from the IO code. An update of the Prometheus library was included in the changes to make sure the latest version of this dependency was used.

In accordance with #635, the image references should be fixed now. Please see the additional optional test result below.
