MT#56358 Test new b_outbound direction in invite_hm

Scenario invite_hm has been extended to test new direction
b_outbound.
Kamailio proxy now is expected to create header OutboundBlegHeader with value
"blegvalue".
The new invite_hm scenario will provision an additional header manipulation and will
check if this header has been correctly produced by kamailio proxy.
