Support K/V Secret Engine

[rizvisx]

I am trying to fetch kv secrets with EndpointResponse like this

$response = $client->sendApiRequest(
		  	'GET',
            '/v1/secret/data/creds',
            EndpointResponse::class);

However, In the EndpointResponse class the data is never being set in the properties as this condition below never meets to find the key in the class. there is a declaration for $metaData, but we get metadata in $key below. Also, since there is no $data property it fails on this condition again.

if (property_exists(static::class, (string) $key)) {

So, adding these missing properties gives me data in the response.

 protected $metadata;
 protected $data;

Now, I am new to Vault so I may be doing things wrong way. Looking forward for your feedback.

Thanks !!

Hey! Currently vaultPHP only supports the transit secret engine - so the K/V secret engine is not implemented. Feel free to adapt the current implementation from SecretEngines/Transit to support K/V and open a pull request. Every file in that folder is the abstraction between api calls and mapping to a data object that gets parsed and finally served as a response dto.
