Better handling of index error p2p_links nodes and other fields in core_interface / l3_edge schema

[gmuloc]

  p2p_links:
    # Pe_P
    - nodes: [pe11-sav366, p11-brv350, pe11-sav366, p12-brv350]
      interfaces: [Ethernet43/1, Ethernet1/1, Ethernet44/1, Ethernet1/1]
      profile: pe_p_profile
      id: 1

This is accepted but fails sadly

The full traceback is:

First idea was to limit the llength in the list
