Add documentation and examples for microk8s

[karlmutch]

As a developer
I want to use the platform-services poc with microk8s
In order that laptop, VMs, or EC2 machine instances can be used for experimentation

[karlmutch]

A strong possibility exists that microk8s support will be migrated to minkube due to lagging support for Istio in microk8s

[karlmutch]

microk8s appears to have gotten some attention and has been upgraded to 1.3.x

Now that we are using LetsEncrypt with Istio microk8s might be delayed until a solution without host name verification can be used.
