Handling of patches and patchesStrategicMerge

[0x-shanks]

Is your feature request related to a problem? Please describe.
I want to visualize the relationship between patches and patchesStrategicMerge and the patched manifest files.

Describe the solution you'd like
Display a manifest file patched with patches or patchesStrategicMerge, for example

/
├── overlays/production
 |  ├── base
 |   │  └── base/a_service
 |   │      ├── deployment.yaml (->p1)
 |   │      └── service.yaml
 | └── a_service/deployment.yaml (p1->)
└── overlays/staging
    ├── base
     │  └── base/a_service
     │      ├── deployment.yaml (->p2)
     │      └── service.yaml
    └── a_service/deployment.yaml (p2->)

p1 and p2 are the patch indices, and the arrows indicate whether you are the patcher or the patched.

Describe alternatives you've considered
Use color to make it easier to see which manifests are being patched.

#23
Added the ability to display the source path when it is specified in PatchesStrategicMerge
However, inline patching is not yet supported.
