How to: Global basic auth
Global basic auth protects all routes. This is useful for protecting endpoints during development and testing. To enable, set the htpasswd file with `--basic-htpasswd=
` or env `BASIC_HTPASSWD=
`.

Reproxy expects htpasswd file to be in the following format:

```
username1:bcrypt(password1)
username2:bcrypt(password2)
...
```
this can be generated with `htpasswd -nbB` command, i.e. `htpasswd -nbB test passwd`
