## Environment details:
* local deployment - standalone jar
* kubernetes versions:
```
{Major:"1", Minor:"15", GitVersion:"v1.15.3", GitCommit:"2d3c76f9091b6bec110a5e63777c332469e0cba2", GitTreeState:"clean", BuildDate:"2019-08-19T11:05:50Z", GoVersion:"go1.12.9", Compiler:"gc", Platform:"linux/amd64"}
```
## Steps to reproduce the issue:
1. Configure the invoker to use KCF
1. Create a service user without access to the `--all-namespaces` / `default` namespace via RBAC
1. Use a kubeconfig that doesn't have a namespace set and uses the service user token
## Provide the expected results and outputs:
Prewarm Containers should start.
## Provide the actual results and outputs:
Prewarm containers don't start and the invoker isn't even listed in: `http://<controller_host_port>/invokers`.
