Simple Golang caching proxy server

Features:

1. Works as explicit HTTP/HTTPS proxy
2. HTTP responses are passed from origin. If a picture requested it is saved to a database (PostgreSQL). If already saved picture is requested it is sent from cache.
3. DB writes are pipelined and performed in their separate routine (no concurrent writes)
4. HTTPS connections are being tunnelled
5. Upon pressing Ctrl-C requestes are waited to be completed and DB jobs are waited to be done, then the server is closed.
