Model->getMetadata TypeError

[timbit123]

Hello I have an error with the function, it can return an array not only a string For exemple if you call it with ->getMetadata('labels')

"Return value of Maclof\Kubernetes\Models\Model::getMetadata() must be of the type string or null, array returned"

Thank you

This should be fixed after merging https://github.com/maclof/kubernetes-client/pull/118

For now this can be used instead

->toArray()['metadata']['labels']
