remote: introduce remoteGetSchedulerParametersFlags

* daemon/remote.c (remoteDispatchDomainGetSchedulerParameters):
New function.
* src/remote/remote_driver.c (remoteDomainGetSchedulerParameters):
Likewise.
* src/remote/remote_protocol.x
(remote_domain_get_scheduler_parameters_flags_args)
(remote_domain_get_scheduler_parameters_flags_ret): New types.
(remote_procedure): New RPC.
* src/remote_protocol-structs: Likewise.
