Create Cloud Connector developer docs
We already document the technical foundations of Cloud Connector, for example:
Moreover, some of these development aspects are spread out over several other documents because they are specific to a particular system involved, such as the AI gateway, or narrowly scoped to a feature, e.g. Code Suggestions: https://docs.gitlab.com/ee/development/code_suggestions. Where these exist, they are usually written with SaaS in mind.
We should provide step-by-step instructions for how to actually work with all that, so developers can refer to this when making contributions or testing locally. We should write these docs so that they can apply to all Cloud Connector features, not just Code Suggestions.
