From: Chun Feng Wu <wucf@xxxxxxxxxxxxx>
Support throttlegroup lifecycle management by the following implementation:
* New methods defined in "include/libvirt/libvirt-domain.h"
* And they're exported in "src/libvirt_public.syms"
* Corresponding internal API is defined in "src/driver-hypervisor.h"
* Public API calls are implemented in "src/libvirt-domain.c"
* Wire protocol is defined in "src/remote/remote_protocol.x"
* RPC client implementation is in "src/remote/remote_driver.c"
* Server side dispatch is implemented in "src/remote/remote_daemon_dispatch.c"
* Also "src/remote_protocol-structs" is updated
* Yu Jie Gu <guyujie@xxxxxxxxxxxxx> helped add
remote_domain_set_throttle_group_args in src/remote_protocol-structs
to fix issue reported by check-remote_protocol
