  Modify the ip_pipeline application to build the hierarchical scheduler
with default subport bandwidth profile. It also allows to configure
a subport with different subport bandwidth profile dynamically

As discussed, it is probably better to merge these two tables into one.

struct subport_profile_params {
	struct rte_sched_subport_params params;
	rte_sched_subport_profile_params profile;
};

struct subport_profile_params subport_profile[TMGR_SUBPORT_PROFILE_MAX];

It avoids confusion and also minimizes the app changes.

The same should be done for the SoftNIC code.
