lxc: use live/config helper
Based on qemu changes made in commitsae523427and659ded58. * src/lxc/lxc_driver.c (lxcSetSchedulerParametersFlags) (lxcGetSchedulerParametersFlags, lxcDomainSetBlkioParameters) (lxcDomainGetBlkioParameters): Use helpers. (lxcDomainSetBlkioParameters): Allow setting live and config at once.
