There was a problem hiding this comment.
Most comments are minor things...
There is a file test-manifest-roundrobin.yml which seems to be some leftover.
I don't think we should modify spec/unit/messages/validators_spec.rb. I see that this was already done for the other route options, but from my point of view this file is more for generic validators and not for specific ones. The tests should be moved into a file route_options_message_spec.rb.

This Pull-Request replaces #4696.
This Pull-Request adds support for hash-based routing to Cloud Controller.
Summary:
The routes model is enhanced as follows:
hashis added as a validloadbalancingoptionhash_headeris added as a per-route option. The option is mandatory whenloadbalancing=hashhash_balanceis added as a per-route option. The option is optional whenloadbalancing=hashValidation of these options is added when creating and updating both via API and via manifest. All validations that do not need the context of a potentially existing route during an update, are executed in the message:
Further validations and cleanups are performed on the route model, as they need the context of existing routes:
hash, then Hash Header must be specifiedThe route options are still stored as a raw JSON string in the routes table.
