'Do not run on' Timeframes for e2e_appmon

Idea created by fugatedg on Nov 7, 2018

    Writing synthetics daily/weekly for our applications, we are tasked to put in exclusion for application downtime/maintenance.  For the e2e_appmon probe, we are only limited to excluding the entire day when we do not want a script to execute.  If a maintenance window is only for four(4) hours, we need to be able to exclude it from executing only for the four(4) hours and not the entire day.  Day & Time ranges are needed for the 'Do not run on', instead of just days; as it is for the 'Only run on' option directly above within the Scheduling tab for the script config.
