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.

先定位 init 腳本，並檢視 deployment 選項的定義方式。釐清私有 registry 的 endpoint 與提交行為，接著判斷如何收集並傳送 server-uri 和 support-email。完成的標準是：init 腳本中的 opt-in 選項可以將這些欄位提交至 Solid Community registry。
