Allow auto creation of namespaces when possible

[lewismarshall]

At the moment, kb8or will deploy to namespaces based on kb8or environment name. It will fail on versions of kubernetes where namespaces need to be explicitly created.

Allow namespaces to be created automatically if they don't exist e.g. when deploying to nfidd-vagrant, pass kubectl this yaml:

apiVersion: v1
kind: Namespace
metadata:
  name: nfidd-vagrant

This is more of a policy issue. IMO if cluster denies namespace auto creation, then should kb8or be creating them?

[lewismarshall]

Kb8or will not be arbitrarily creating any namespace - only one for the kb8or environment in use..

If the policy is not to allow creation of Namespaces, then that's fine too - kb8or won't be able to create them.

If this isn't implemented then the user would only do it immediately by creating a Namespace document manually and adding it to either the kb8or deploy or with kubectl directly.

Just upgraded to kerbernetes v1.1.1 and the namespace is no longer dynamically created. Will implement this now.
