What does this PR do?
This PR makes it so we don't check for the kubernetes auth_token if TLS certs are already provided for authentication to the kube-apiserver (when the dd-agent is running on the host). The pre-existing dd-agent should work, but would log noisy "Token not found at /var/run/secrets/kubernetes.io/serviceaccount/token" errors to the logs.
Motivation
What inspired you to submit this pull request? Less noisy logs :)
