• Simple change to allow for "spanning-tree guard" config
• Extended existing datamodel with additonal option:

ethernet_interfaces:

  spanning_tree_guard: < loop | root | disabled >

• Skipped doc. update because other spanning-tree options are also not explicitly rendered in doc (besides in the config snippet)

@ccsnw Can I ask you to add the same to port_channel_interfaces so we avoid too many deviations? Thanks
