stp: Introduce tests TC_dyn_(2)asp_as_rkm_permitted

These tests allows testing behavior of scenarios related to dynamic ASP/AS/RKM improved/fixed in libosmo-sigtran.git Change-Ids: I986044944282cea9a13ed59424f2220fee6fe567 I85948ab98623a8a53521eb2d2e84244011b39a93 I3dffa2e9c554f03c7c721b757ff33a89961665b5
