   The appcookie feature was primary driven by the netscalar implementation (if I recall correctly). Per the haproxy docs `As of version 1.6, appsessions was removed. It is more flexible and more
   convenient to use stick-tables instead, and stick-tables support multi-master
   replication and data conservation across reloads, which appsessions did not.`. We can explore if an upgrade path is possible.
   The LB feature needs some overall cleanup and fixing, other than the tcp round-robin (most preferred use-case), SSL off loading etc don't work, as they were primarily netscalar driven in the past.
