Dataplane API 2.x and newer versions

[akutz]

The version of DP API that is built and ships with this image is 2.1, and the latest version of DP API is 2.8 (with HAProxy Enterprise using 2.7). We have a question as to whether a DP API 2.1 client is comaptible with 2.7/2.8? We also tried updating the version of DP API in this repo to 2.7, but the binary fails to start due to a now invalid config file.

Can someone from HAProxy please:

• Answer the question about compatibility?
• Help figure out what changes need to occur in the DP API config file to make it compatible with 2.7/2.8?

Thanks!
