    When ConsumeAMQP creates a FlowFile with an attribute named 'amqp$contentType' - we should
consider also writing that value to the 'mime.type' attribute, as this is the 'standard attribute'
that we use to determine the content type. This is used, for instance, by some of the Content
Viewers. So if it's text/json, for example, we know how to render that if viewing content
via Provenance.
