Host state capabilities include multi-level information, like
cpu features are presented in capabilities:cpu_info:features, cpu
core number in capabilities:cpu_info:topology:cores.
Multi-level capability check maybe helpful in some situation, like
user want to make sure host support SSE3 instructions or AES-NI, or
user want to make sure the host has >4 cores for SMP instance. Current
capability filter does not support these requirements.
To support multi-level check, also add scope to capability filter,
so, now capability filter will handle no-scope extra_specs, or scope-format
as "capabilities:xxx:xxx" etc.
