Allow override of DEPLOY_APPS

When using the local setup to debug issues or develop some feature I find it useful to not deploy sample applications.
By starting with an "empty" cluster it is much easier to analyse the controller logs since there won't be any additional noise.

```
K8GB_LOCAL_VERSION=test DEPLOY_APPS=false make deploy-full-local-setup
```
