Consolidate catalogd and operator-controller Kustomize configs

[OchiengEd]

Consolidate the catalogd and operator-controller kustomize configuration dirs. e.g.

$ tree -d config
config
├── catalogd
└── operator-controller

Goal: We should be able to render separate overlays for each project. However, de-duplication of kustomize configuration files could be done.
