Enhancement: provide more information about agent in release summary reports

[sophia-guo]

When there are failures that pass on auto rerun it helps if release summary reports provides machine/agent information, e.g. name of original machine tests failed on and rerun machine tests passed on. The note would help to confirm if it's machine related without to check the deep history.

Relating this to the EPIC #649 which contains a growing list of improvements to the release summary report.
