autoconfig: Allow mixing _FILE variables

We do not always need to configure variables as either a file or not for
all variables.

Instead, allow us to mix-match variable storage. This allows us to keep
all non-critical variables in regular (env) variables, but keep the
password in a (secret) file only location.
