Support minutes in mark-for-op actions

Is your feature request related to a problem? Please describe. mark-for-op just supports days and hours. These units are too big for some use cases.

Describe the solution you’d like mark-for-op should also support minutes and maybe the other units supported by datetime.timedelta: seconds, microseconds, milliseconds, and weeks. https://docs.python.org/3/library/datetime.html#datetime.timedelta

Describe alternatives you’ve considered mark-for-op could also accept a float as hours, but this would be more complicated to implement and less reliable.

I’m game to support numbers here in the schema for hours.

oh, that’s curious… I am using it for the asg resource and figured it was all the same. Sure enough, asg is an override of TagDelayedAction and changes the schema from integer to number. We should just change the default TagDelayedAction schema to numbers instead of integers. Up to @kapilt if also adding minutes is reasonable.
