DISPATCH-1688: Inject literal log lines into scraper output
> Scraper needs a way to inject debug statements into log data web page
> ---------------------------------------------------------------------
>
> Key: DISPATCH-1688
> URL: https://issues.apache.org/jira/browse/DISPATCH-1688
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Tools
> Affects Versions: 1.12.0
> Reporter: Charles E. Rolke
> Assignee: Charles E. Rolke
> Priority: Major
> Fix For: 1.13.0

> For debug purposes one may create log statements originating from log source *_SCRAPER_* and these messages are copied verbatim into the scraper main output web page. This will put the debug scraper logs in temporal order along with the AMQP traffic.
> Note that the SCRAPER log source does not need to be created in the router's log sources setup but can be generated on-the-fly at any time in any module.
> A log statement like
> {noformat}
> qd_log(qd_log_source("SCRAPER"), QD_LOG_CRITICAL, "Crazy event 42 happened!"
> {noformat}
> will result in a scraper display like
> {noformat}
