m/node/kubernetes/pki: refactor out CA functionality
This factors out all non-k8s-specific CA functionality from
metropolis/node/kubernetes/pki into metropolis/pkg/pki.
This will allow us to re-use the same PKI-in-CA system to issue
certificates for the Metropolis cluster and nodes.
We also drive-by change some Kubernetes/PKI interactions to make things
cleaner. Notably, this implements Certificate.Mount to return a
fileargs.FileArgs containing all the files neede to use this
Certificate.
Test Plan: covered by current e2e tests. An etcd harness to test this independently would be nice, though.
