The 'require' CPU threads policy ensure that hosts are required to have an SMT architecture and that it be possible to schedule an instance utilising the thread siblings. The 'require' policy should and will only be used when explicitly requested by the instance or image. The existing 'prefer' policy (though it wasn't called this before) is retained and will be used both when requested and as the default, per the spec. A stub is included for the remaining 'isolate' case. It is necessary to add a filter to exclude hosts with no sibling support. This ensures that hosts that could not implement this threading policy are quickly discarded. Finally, some tests that tested the 'require'-like aspects of the 'prefer' policy are reworked to request this policy explicitly.
