  1. prov/tcp: Add support for active TCP port range 

    There is a need (e.g. firewall rule) to limit TCP ports used for
active connections.

The use case is DOAS clients started by MPI accessing DAOS servers
behind firewall.  Since MPI and DAOS may not want to share the same
port restriction, add active port range support under domain object
using fi_set_val.

Define FI_TCP_DOMAIN_ACTIVE_PORT_RANGE to take a
struct xnet_port_range * of low and high port range.

Sample:
  struct xnet_port_range range = { .low = 5000, .high = 6000 };
  fi_set_val(&domain->fid, FI_TCP_DOMAIN_ACTIVE_PORT_RANGE, &range);

To disable the range, set low and high port range to 0.

If the source address for an active connection contains a port
number, it will be used over a defined port range.

  2. prov/tcp: Set passive port range via fi_set_val 

    For applicaitons that cannot set environment variables via shell or setenv
API, add fi_set_val support to fabric object to set FI_TCP_PORT_LOW_RANGE
and FI_TCP_PORT_HIGH_RANGE values.

Define FI_TCP_FABRIC_PASSIVE_PORT_RANGE for fabric object taking
struct xnet_port_range * parameter set with desired low and high port range.

Sample:
  struct xnet_port_range range = { .low = 9000, .high = 9100 };
  fi_set_val(&fabric->fid, FI_TCP_FABRIC_PASSIVE_PORT_RANGE, &range);
