pScheduler style 'comments' in JSON files.
JSON "keys" that start with # will be considered "comments" and ignored when parsing the config file.

example /etc/perfsonar/psconfig/pscheduler-agent.json:

{
	'remotes': [],
	'#comment': "example"
}

previously gave an error:

...Error: Additional properties are not allowed ('#comment' were unexpected)

now - no errors.

code from pScheduler

Looking good to me. But maybe we could also include python3-pscheduler as a dependency so as not to duplicate the code. @arlake228 shall we push this to 5.3.0 so to better review this?
