tools/html_report: Make html report generation autotest generic
The html report tool was a bit too tied to KVM autotest, and that
was not necessary. Turn it into a generic module that can be used
by any autotest job, encapsulate the main worker function into
autotest API so we don't need to exec it in a subshell, fix naming
of the report and CSS details.
