DOC: Fix value type of pox-maxconn annotation from integer to string

[FabioDavidF]

The problem:

The example usage of the pod-maxconn service annotation uses an integer value, while annotations require string values.

Since Annotations in kubernetes must have string values, I think the example should be a string aswell

The solution:

I don't have permission to push a new branch in order to open a PR, but it would be a 1 liner:

Hi @FabioDavidF
Thanks for reporting it.
Im fixing this.
annotations.md is generated, the change has to be done on doc.yaml but as you say it's a 1 liner.

Thanks for the follow-up @hdurand0710.

Quick question: Is haproxy still accepting open contributions to this project?
