Description of problem:
machine get Running when set CapacityReservationsOnly on spot instance, but this combination should not be allowed, because I checked on AWS console it's not allowed https://drive.google.com/file/d/1Rr9royBaOGlT-J8Q2gG2r3GXc3yrBK48/view?usp=sharing we should give webhook for this case to keep consistent with AWS.
