fib: Changes to interpose source
Type: improvement 1) stack the interpose on any path-extensions (e.g. labels) from the next best source 2) allow more than 1 source to contribute a DPO for a given prefix Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: Idc2fbb36cfbd2387081765d8af0f1fbe61612160
