Added traits support to the scheduler. A new flavor extra spec is added to

as below:

``trait:<trait_name>=required``, for example:

- trait:HW_CPU_X86_AVX2=required

- trait:STORAGE_DISK_SSD=required

The scheduler will pass required traits to the

the only valid value is ``required``. Any other value will be considered

invalid.

The FilterScheduler is currently the only scheduler driver that supports
