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
=== Bridge STP Basic
==== Description
Verify that a fully connected mesh of 4 DUTs is pruned to a spanning
tree.
Since the mesh contains 3 redundant paths, can infer that a spanning
tree has been created if all host interfaces can reach each other
while exactly three links are in the blocking state.

==== Test sequence
. Set up topology and attach to target DUT
. Configure a bridge with spanning tree eneabled on dut a, b, c, and d
. Add an IP address to each host interface in the 10.0.0.0/24 subnet
. Verify that exactly three links are blocking
. Verify that host:a can reach host:{b,c,d}
