adding basic auth

[eoprede]

This is an extremely basic way to add basic authentication for oxidizied-web. User can set environment variables BASIC_AUTH_USERNAME and BASIC_AUTH_PASSWORD, after which all the requests to the oxidized will need to provide basic authentication. LibreNMS integration remains functional, as one can provide UN/PW in the URL.

I am aware that one can easily add reverse proxy to achieve the same functionality, but I feel that having ability to do it quickly and easily via environment variables would simplify things for those who choose to run oxidized in container environments.

Node: I'd like to solve the problem in a more generic way (see Issue #353), keeping the PR open until the more generic way is done.
