Why I did it
SONiC currently does not identify 'EdgeZoneAggregator' neighbor. As a result, the buffer profile attached to those interfaces uses the default cable length which could cause ingress packet drops due to insufficient headroom. Hence, there is a need to update the buffer templates to identify such neighbors and assign the same cable length as used by the T1.
How I did it
Modified the buffer template to identify EdgeZoneAggregator as a neighbor device type and assign it the same cable length as a T1/leaf router.
How to verify it
Unit tests pass, and manually checked on a 7260 to see the changes take effect.
