This implements Webauthn. Old devices can be used to authenticate via the appid compatibility layer which should be automatic. New devices will be registered via Webauthn, and devices which do not support FIDO2 will no longer be able to be registered. At this time it does not fully support multiple devices (backend does, frontend doesn't allow registration of additional devices). Does not support passwordless.
This commit replaces github.com/spf13/viper with github.com/knadh/koanf. Koanf is very similar library to viper, with less dependencies and several quality of life differences. This also allows most config options to be defined by ENV. Lastly it also enables the use of split configuration files which can be configured by setting the --config flag multiple times.

Currently if a `log_file_path` is defined Authelia will redirect all logging from standard output to said defined location. This change allows users to keep standard output logging along with a defined `log_file_path`.
This change adds the ability to format Authelia's log output as JSON.
Example below:
```
{"level":"info","msg":"Logging severity set to info","time":"2020-01-01T00:00:00+11:00"}
{"level":"info","msg":"Authelia is listening for non-TLS connections on 0.0.0.0:9091","time":"2020-01-01T00:00:00+11:00"}
```
