Include number of retries in email status

If you have an active alert that sends an email for a scheduled testsuite, then those emails will contain information such as Duration, Completed Steps etc.

For these types of alert emails, it would be useful to also have info about the number of "Retries".

For example, after "Completed steps" to have an entry "Retries":

This entry would make sense for all alert types when results have status:

• Passed

• "Failed"

• "Bugbug internal error"
