rOPSaa208267aeb6: Reduce the length of GRE interface name
Summary

The define IFNAMSIZ in Linux kernel defines the maximum length of an interface
name. By default, 16 characters, including the final '\0'.

As such, names like gre-drake_via_router-001 are too long.

gre-drake seems to be descriptive enough, as a node has only one GRE tunnel
if it's not our router.

Reference: include/uapi/linux/if.h

Ref T1832

Test Plan

Deploy on cloudhugger, ifconfig gre-drake
