local-node: periodically send link-measurement requests

Browse Source 
Send link-measurement requests to every supporting local-sta in order to
acquire information to assess the link-quality bi-directional.

The link-measurement request is sent each configurable interval. It can
be disabled by configuring the interval to 0.
