feat: Add after:run event

[chrisbreiding]

• Addresses TR-542
• Partially addresses Add new plugin events 'before:spec', 'after:spec', 'before:run', 'after:run' #6665

User facing changelog

• You can now listen to a after:run event in the plugins file. See the documentation for more information (TODO: link to doc).

Additional details

• The event fires after the run.
• It only fires in run mode.
• If running parallel, it will run for each machine running.
• The event handler receives one argument, an object with the result of the run. It's the same results the module API receives.
