telecom: Introduce the local priority attribute into the data set. 

The Telecom Profiles G.8275.1 and G.8275.2 have invented a new
per-port and per-clock attribute, not in 1588, called "localPriority".
The use of this attribute is a distinguishing feature of the telecom
data set comparison algorithm.

This patch adds the attribute, hard coded to its default value.
