init script option to submit pod info to solid community registry

We discussed it today during Solid Community Call, actually @jaxoncreed suggested it could go into init script.

I think to get started we can just have a private registry managed by solid community (just few people having access to data). Minimal data I would see needed:

• server-uri
• support-email

Later it can act as seed for public solid providers directory, for now it would at lest give community some notion of how many pods got deployed out there and contact list where we could now and then send out a survey requesting feedback about their deployments.

まず init スクリプトを見つけ、deployment オプションがどのように定義されているかを確認します。プライベート registry のエンドポイントと送信動作を明確にし、server-uri と support-email をどのように収集して送信するかを判断します。init スクリプトの opt-in オプションによってこれらのフィールドを Solid Community registry に送信できれば完了です。
