Support a db backend for high availability scenarios

[miraculixx]

To enable running chp multiple times in a HA scenario it needs to support a database backend (instead of in-memory, as currently).

Requirements:

• implement store.DatabaseStore using sqlalchemy for max flexibility
• add tests
• make this an optional requirement, e.g. pip install configurable-http-proxy[sqla]

Hi @miraculixx That sounds like a cool idea.
I would be very open to merge a PR with this addition.

So I understand it better - does the current javascript based configurable-http-proxy have a database store already ?
Or how do you handle this with it with the current CHP ?
Trying to understand if this is a feature parity issue that should be documented in the README or is this a new request for the proxy which doesn't exist so far

Hi @AbdealiJK, thanks for your feedback!

does the current javascript based configurable-http-proxy have a database store already

Unfortunately no, but it does have support for pluggable storage, as you know I guess, and there is this Redis implementation. However, I need one that works with an SQL DBMS. Since my stack is almost entirely Python, your project would be straight forward.

I would be very open to merge a PR with this addition.

Glad to hear! Please see #11. I also added #10 to automatically run unittests.
