add kube validator

+To initialise a network:
+
+ - delete everything (including persistant volume claim)
+ - deploy everything except the deployment
+ - wait until the job has finished, then deploy the deployment
+ - check job pod logs for the validator account backup phrase :\
+
+Examples of using light client with the node:
+
+ - Get the status `gaiacli status --node <node's-ip-address>:46657 --chain-id kava`
+ - Send coins `gaiacli send --name <your-key-name> --to <receiver's-address> --amount 10kavaToken --node <node's-ip-address>:46657 --chain-id kava`
+ - Run the rest server `gaiacli rest-server --node <node's-ip-address>:46657 --chain-id kava`
+ 
+Notes
+
+ - There's two persistant volumes, for `.gaiad` and for `.gaiacli`, because their default locations are awkward.

+This Dockerfile is to build cosmos-sdk. It needs to be in the cosmos-sdk repo to build.
+
+It modifies the existing Dockerfile in the cosmos-sdk:
+
+ - split up commands to make use of layers to make rebuilds and uploads faster
+ - switch `ENTRYPOINT gaiad` to `CMD gaiad` to save typing `--entrypoint` all the time
