Subject: [PATCH] Run e2e Tests Against Multiple k8s Versions

Enable a build matrix in Travis CI to run the e2e tests against
multiple k8s versions. Additionally update kind to v0.7.0 which adds
support for k8s v1.17.

Replaced command "kind get kubeconfig-path" with "kind get kubeconfig"
because the "kubeconfig-path" subcommand is not valid with kind v0.7.0.
