core.configmanager: Add function for getting secrets from separate files
Idea is to enable easily retrieving of secret values from files outside
of the config, e.g. via the method used by systemd credentials.
CREDENTIALS_DIRECTORY is expected to be set by the process manager
invoking Prosody, so being unset and unavailable from prosodyctl is
going to be normal and a warning is reported in that case. Care will
have to be taken to make it clear that prosodyctl check will not work
with such values. An error is thrown if the directory is unavailable
when running under Prosody.
