This patch aims to fix some of the inconsistencies in error reporting,
for example "Internal error" or "Console request failed" instead of
"password authentication failed for user '<NAME>'".
This is needed to forward the `ClientKey` that's required
to connect the proxy to a compute.

* [proxy] Add SCRAM auth
* [proxy] Implement some tests for SCRAM
* Refactoring + test fixes
* Hide SCRAM mechanism behind `#[cfg(test)]`
Currently we only use it in tests, so we hide all relevant
module behind `#[cfg(test)]` to prevent "unused item" warnings.
