[aerogear-dev] New diagrams for UPS clustering and metrics collection improvements

Hi guys, I'm finishing diagrams for the docs that cover how UPS using JMS works (or will work in a near future) internally. The concepts illustrated in (2) and (3) are not yet implemented, they are just proposals, that's why I would appreciate if you go through them, read callouts, and if you have idea how to improve them, let us know! *1. Overall picture:* https://docs.google.com/drawings/d/13IsJWPSJNYXtst-UVxQYmzH36C_EXQMYYr_jc... *2. Token loading, dispatching and metrics collection in detail:* https://docs.google.com/a/fryc.eu/drawings/d/12cUrYf7ACLYEoYsIWul2szN3lmQ... *3. Concept of limiting number of push dispatching sessions * *(cluster-wide):* https://docs.google.com/a/fryc.eu/drawings/d/12cUrYf7ACLYEoYsIWul2szN3lmQ... There are more details coming in form of UPS guide docs / appendix. Cheers! ~ Lukas
