Allow authorization handler to disable openapi

See: #671

[mevdschee]

If you add the 'authorization' middleware and this config:

'authorization.tableHandler' => function ($operation, $tableName) {
    return $operation != 'document';
},

Then none of the tables will be documented in the openapi output. This does not disable the entire openapi output, but it does what was intended.

This can now be solved with the new "pathHandler"

'authorization.pathHandler' => function ($path) {
    return $path === 'openapi' ? false : true;
},

Thanks to the PR of @florianorben (thank you!).
