254629cf16 Added support for annotation session-cookie-change-on-failure 
1. Session cookie is updated on previous attempt failure when `session-cookie-change-on-failure = true` (default value is `false`).
2. Added tests to check both cases.
3. Updated docs.

60b983503b Consistent hashing to a subset of nodes. It works like consistent hash, 
but instead of mapping to a single node, we map to a subset of nodes.

Add canary annotation and alternative backends for traffic shaping
 2018-11-06 12:22:16 -08:00
Conor Landry
412cd70d3a implement canary annotation and alternative backends 
Adds the ability to create alternative backends. Alternative backends enable
traffic shaping by sharing a single location but routing to different
backends depending on the TrafficShapingPolicy defined by AlternativeBackends.

When the list of upstreams and servers are retrieved, we then call
mergeAlternativeBackends which iterates through the paths of every ingress
and checks if the backend supporting the path is a AlternativeBackend. If
so, we then iterate through the map of servers and find the real backend
that the AlternativeBackend should fall under. Once found, the
AlternativeBackend is embedded in the list of VirtualBackends for the real
backend.

If no matching real backend for a AlternativeBackend is found, then the
AlternativeBackend is deleted as it cannot be backed by any server.
