Document network access requirements

Problem/Motivation

We currently do not document the network access requirements for the server when using the module.

While most of it may seem to be expected explicitly documenting the network access requirements will provide an official source for site owners to provide to their network teams and provide a single point of refrence for the module to disclose the connection it makes.

Steps to reproduce

Proposed resolution

Document the network accesses required.

Remaining tasks
