feat: Sane default config

[portly-halicore-76]

Feature Request

Describe the Feature Request

In both the current and future implementation (#153) of configuring the operator using config we require that a config needs to be set for the operator to work. #153 implements even not reconciling paas(ns)'es while no config has been applied.

Please refactor to start the operator, and do some basic reconciling against a default config with sane defaults.

Describe Preferred Solution

Add a sane default config to the operator. If the user applies his own config, overwrite the default one.

Describe Alternatives

Everything regarding the paasconfig-controller and PaasConfigStore
