test/common: Allow rpc_cmd() to execute multiple commands



This allows to pass to rpc_cmd() sets of commands via stdin. E.g.:

rpc_cmd <<-CMDS
	bdev_malloc_create -b Malloc0 32 512
	bdev_malloc_create -b Malloc1 32 512
	bdev_malloc_create -b Malloc2 32 512
CMDS

Since rpc.py is already running in a server mode, this is slightly
faster than grouping commands and running scripts/rpc.py directly.
