v2: break down the case to small cases with separate flags
* Use setVcpusFlags API to set domain vcpus with flags
* 3 cases added, each only deal with one set flag value as in
config, live or maximum
* cases are independent on domain states, API will report error
if not suitable for certain states
* the sample conf is only one scenario of hotplug domain vcpus
v3: merge config and maximum case to config
* maximum flag can only work when domain is shutoff, merge it
to config case to simplify code
