smsgw: productionize, implement kube/mirko

This productionizes smsgw.

We also add some jsonnet machinery to provide a unified service for Go
micro/mirkoservices.

This machinery provides all the nice stuff:
 - a deployment
 - a service for all your types of pots
 - TLS certificates for HSPKI

We also update and test hspki for a new name scheme.
