[j-nsp] Transfer some task from MX to VRR

[Robert Hass]

Hi
Just readed release notes for 14.2 and I found that starting this release I
can transfer some task to external VRR.

We have lack of compute power mostly on MX80.

So my idea is to move all BGP from MX80 to VRR. But how it can be performed
for external BGP sessions where I have just /30 or /31 subnets to customers
? (of course without ebgp multihop).
