Use context in Kubernetes authentication

[nicolascb]

Is your feature request related to a problem? Please describe.

Today the Login method via Kubernetes receives a context but does not use it: api/auth/kubernetes/kubernetes.go#L70

Describe the solution you'd like

Using the latest version of the api, we can solve this problem like this:

api/auth/kubernetes/kubernetes.go#L77

-       resp, err := client.Logical().Write(path, loginData)
+       resp, err := client.Logical().WriteWithContext(ctx, path, loginData)

Hi @nicolascb!

Thank you for this suggestion! Now that we have WithContext methods, this change is quite easy. I have a PR that takes care of all of our current auth helpers in on shot: #14775

I have merged the PR. Thank you for contributing to HashiCorp!
