Travis CI test matrix

GCE instances

Here is the test matrix for the Travis CI gates:

Network plugin	OS type	GCE region	Nodes layout
canal	debian-8-kubespray	asia-east1-a	default
calico	debian-8-kubespray	asia-northeast1-b	default
flannel	centos-7	europe-west1-c	default
calico	centos-7	us-central1-b	default
weave	rhel-7	us-east1-c	default
canal	coreos-stable	us-west1-b	default
canal	rhel-7	europe-west1-c	separate
weave	ubuntu-1604-xenial	europe-west1-d	separate
calico	coreos-stable	us-central1-f	separate

Where the nodes layout default is that is given in the example inventory file. And the separate layout is when there is only node of each type, which is a kube master, compute and etcd cluster member.

Note, the canal network plugin deploys flannel as well plus calico policy controller.

Hint: the command

bash scripts/gen_matrix.sh

will (hopefully) generate the CI test cases from the current .travis.yml.
