[libvirt] [PATCH 1/8] schedinfo: Define new API virDomainSetSchedulerParametersFlags

[Osier Yang]

Flags may include VIR_DOMAIN_SCHED_PARAMS_LIVE and
VIR_DOMAIN_SCHED_PARAMS_PERSISTENT, the first one means changing
the domain scheduler setting only for running domain config, and
the later one means changing both the running and persistent domain
config.

Both flags require domain is running, VIR_DOMAIN_SCHED_PARAMS_LIVE
is used by default.
