Yes, first thing will not commit.  Spent most of a day carefully going
through every available option, testing, re-testing doc searching, etc...

Was totally blown away, and spent several hours chewing on our SE about it.

In my mind, the default is fine.  It is consistent with normal behavior
and there are times when a shared policer would be desired.  The lack of
a instance specific option though, that is stupid beyond belief,
shocking surprise.

I layed into SE team on this one just are hard as I did about tri-color
policers.  Juniper went through all the trouble to create a nice
tri-color system but left out the most useful feature already in
standard policers... logical-bandwidth
