Deprecate link-detect and don't display it in show running-config

Ticket: CM-11808
Reviewed By: CCR-4972
Testing Done: Usual stuff

link-detect is on by default, and has been so since the first release
of Cumulus Linux. So, in the light of not displaying defaults, don't
display link-detect if enabled, only if disabled.
