Implemented logic to check if the system supports required services. Logical edges with 'requires' fields are mapped only if physical edges provide corresponding services. If not, the test is skipped. This ensures that tests only run when the required services are available in the test system configuration. Fixes #654
=== IGMP basic
==== Description
Verify that all multicast get flooded when no IGMP join exists in the system and
the flooding stops as soon a join arrives

==== Test sequence
. Set up topology and attach to target DUTs
. Configure device
. Start multicast sender on host:data0, group 224.1.1.1
. Verify that the group 224.1.1.1 is flooded on host:data2 and host:data3
. Join multicast group 224.1.1.1 on host:data2
. Verify group 224.1.1.1 is received on host:data2
. Verify that the group 224.1.1.1 is no longer received on host:data3
