When we use the flavor extra_specs "hide_hypervisor_id" in
AggregateInstanceExtraSpecsFilter, then will retrun False.
So we need correct the extra_specs.
NOTE: The first two files do not exist in stable/train due to
extra specs validators (patch Ib64a1348cce1dca995746214616c4f33d9d664bd)
was introduced in Ussuri.
The last one file has conflict due to the same
bp/flavor-extra-sepc-validators feature
(patch: I8da84b48e4d630eeb91d92346aa2323e25e28e3b)
added in Ussuri.
