use https if available / fix Typing / use Config

[aria1th]

1. Loads from config file. The config file can be placed in webui directory as distributed-config.json

[{"uuid": "worker1", "address": "https://somewhere.example.com", "auth": "username:password"}]

2. Fix Typing Annotation Issues.

3. use session

4. allow https connections with auth.

Future work : lets just put this in always_on script. That will let us actually use nested workers concept, which can call other workers recursively, or we can call this script with API.

This may result some infinite recursion problem too, though, but that should be controlled externally.

Another future work : only use script args if worker has matching scripts.

@papuSpartan Thanks for the review! I fixed most of the issue, except I need some test for mixture of http + https addresses. The pull requested is rebased for dev branch in #17
