[j-nsp] track-igp-metric in LDP

[Chen Jiang]

Hi! Michael

Thanks for your clarification.

Sure, it will let LDP use IGP metric, but is there any benefit?

Cause per my understanding LDP only works for label distributing, not path
selection, and LDP always follows the IGP path, so what is the difference
or benefit to add additional configuration knob to let LDP use IGP metric?

BR!
