In our last maint work we learned that removing Graceful Restart (GR) causes
BGP to restart.  We removed GR from all the non-core network devices, but
decided to delay removing it from border routers holding full routes
and core switches until the TCW, as it will be a bit disruptive when
all the BGP sessions restart on any one of these devices.

Here's the list of devices from which we will delete GR:

fw1.corp.console.scl3.mozilla.net
fw1.corp.phx1.mozilla.net
fw1.phx1.mozilla.net
fw1.releng.scl3.mozilla.net
fw1.scl3.mozilla.net
fw1.svc.phx1.mozilla.net
border1.console.pao1.mozilla.net
border1.console.scl3.mozilla.net
border1.console.sjc2.mozilla.net
border1.phx1.mozilla.net
border2.console.scl3.mozilla.net
border2.phx1.mozilla.net
core1.corp.console.scl3.mozilla.net
core1.corp.phx1.mozilla.net
core1.svc.phx1.mozilla.net

work completed.
We actually left GR configured on border1.sjc2, to be deleted another day, as the convergence
time for this change is a killer.
