[c-nsp] Need working ASR1k pppoe police/shaping

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/bbdsl/configuration/xe-3s/asr1000/bba-xe-3s-asr1000-book/bba-ppoe-ses-q-rad-xe.html

Which basically boils down to:
The following AV-pairs define the QoS policy to be applied dynamically to the session:
"ip:sub-qos-policy-in=<name of the QoS policy in ingress direction>"
"ip:sub-qos-policy-out=<name of egress policy>"


You need to configure the policy-maps on the box first, obviously.
