FR: show internal NOS interface names

[bortok]

TODO

• [x] pull interface names via node-data service as live interface names for cEOS
• [x] UI controls to switch between interface names - static vs live labels
• [x] show live interface names instead of static when requested
• [x] conditional show of the UI controls, only when node-data is working
• [x] switch node names between static and live, in addition to interface names
• [x] avoid redrawing when switching label types (shall keep layout as is)
• [x] shorten live interface names
• [x] format link tooltip
• [x] add LAG links support for tooltips, fixing the labels to be done separately, see #39
• [x] test with other supported types of NOSes
  • [x] cEOS
  • [x] Linux
  • [x] cRPD - interface names are the same, see more on IP address data #24
