based on feedback on rhevm-staff mailing list [1], New Scheduler (policies, units, etc) is missing from rest api. [1] https://post-office.corp.redhat.com/mailman/private/rhevm-staff/2014-April/msg00010.html
it was mentioned in [1] that this may be done for 3.5. if this is indeed already done (even only in master, i.e. for 3.6), please feel free to close this BZ. [1] https://post-office.corp.redhat.com/mailman/private/rhevm-staff/2014-April/msg00010.html
This is already available in 3.5.
