Invalid default configuration

Bug Report

Q	A
Version(s)	all ?

Summary

Default configuration provided is different than documented:

Configuration:

mezzio-authentication-oauth2/config/oauth2.php

Lines 14 to 15 in e4aa82b

    
           'private_key'    => getcwd() . '/data/private.key', 
        
           'public_key'     => getcwd() . '/data/public.key',

Documentation:
https://github.com/mezzio/mezzio-authentication-oauth2/blob/master/docs/book/v1/intro.md#configuration

Generating keys:

mezzio-authentication-oauth2/bin/generate-oauth2-keys

Line 54 in e4aa82b

$dataDir = $dataDir . '/oauth';

Current behavior

In the current configuration we have path set to /data/public.key and /data/private.key while documentation says default path is /data/oauth/public.key and /data/oauth/private.key and also generator put keys in that location.

I believe we have to update the configuration to set whatever is said in the documentation.

It can breaks some applications if someone relies on that "invalid" configuration.

The same for encryption key:

mezzio-authentication-oauth2/config/oauth2.php

Line 41 in e4aa82b

$encryptionKeyFile = getcwd() . '/data/encryption.key';

I would go with the location where the key generator puts the keys, and make sure the documentation is indicating it correctly. Since the docs and key generator are in agreement, I'd consider the configuration to be incorrect here.

	'private_key' => getcwd() . '/data/private.key',
	'public_key' => getcwd() . '/data/public.key',
