Update our processes to reserve time as part of milestone for better validation

Reserve time as part of milestone to validate other team members' features / fixes and file CTI scenarios for these as well. When filing CTI validation scenario, also consider exploratory testing too (if needed).

@rafikiassumani-msft , @adityamandaleeka I've incorporated this into our planning and I'd like to close this unless you think there is more work here.
