Integrate with Gitea.com and self-hosted Gitea

Gitea.io is an open-source, go-based GitHub clone with a free public saas implementation at gitea.com. While it is possible to achieve this integration with the CLI, a direct or simpler way to integrate with gitea.com or a self-hosted instance would allow users to host their site repositories with their other projects, or to create gitea+netlify services with a single or small set of site templates for specific purposes.

Elsewhere, this feature was requested in 2017 at go-gitea/gitea, and netlify-cms has an open issue and closed WIP PR to integrate with Gitea.

@bmackinney Does this help?
