Read configuration dynamically

[thdxr]

Instead of reading the application configuration once and caching it in a GenServer, it should be read on demand when a request is made. This fits normal Elixir convention and doesn't depend on configuration being set in an explicit order.

Following up on this, is a GenServer even necessary?

[olivierbuffon]

I would also be interested by that change. We use Confex in our project and unfortunately because of the current implementation it won't work.

I have a use-case that involves hitting two vault servers. Could really use this. Would a PR be accepted?

[AtebMT]

Absolutely. Most of the recent changes have come from PRs.
