Test Active Active Setup for Load Balancer

[marca56]

Will reduce downtime for customers when an upgrade or restart is required

[deruelle]

@marca56 we should provide a full list of test cases and call flows to be supported as part of the User Story

[marca56]

@knosach or @deruelle ... is there a list of test cases and call flows somewhere for the LB? If not, we can plan a discovery session and write them all down :)

[deruelle]

@marca56 some initial discovery https://docs.google.com/document/d/1d-xkmG3pHyoDWUx89ibGkTU-cP2FAGVcTrDGQ8Wc7ig/edit#heading=h.z6ne0og04bp5. Also we need to ensure all inbound calls - outbound calls (SIP and WebRTC) - HTTP inbound traffic and SMPP inbound and outbound traffic can be handled correctly in active active setup.
