[Question]::Can we replace and Remove yaml keys with single configuration ?

Hi Team,

This question might seem very basic, but i am a new user of `ytt` and still in exploration mode.

I have following templates.
**Base Template:**
```
`---
apiVersion: 1
specification:
versions:
- name: v1
schema:
openAPIV3Schema:
properties:
spec:
myConfiguration:
description: Customized Configuration
`
```

**Key Replace Template:**

```
`
#@ load("@ytt:overlay", "overlay")
#@ load("@ytt:data", "data")
#@overlay/match by=overlay.all
---
apiVersion: 1
specification:
versions:
#@overlay/match by=overlay.all, expects="1+"
- schema:
#@overlay/replace via=lambda left, right: {"properties": right}
openAPIV3Schema:
spec:
new_myConfiguration:
#@overlay/replace via=lambda left, right: {"properties": right}
new_description: Modified Configuration
new_key: avinash
`
```

**Key_Remove_Template:**

```
#@ load("@ytt:overlay", "overlay")
#@ load("@ytt:data", "data")
#@overlay/match by=overlay.all
---
apiVersion: 1
specification:
versions:
#@overlay/match by=overlay.all, missing_ok=True
- schema:
openAPIV3Schema:
properties:
spec:
#@overlay/match when=lambda right: data.values.client == "local_client"
#@overlay/remove
new_myConfiguration:
```

So basically i am trying to rename `myConfiguration` provided `client !="local_client"`, and if then remove `myConfiguration` altogether.

Reproduce the Base Template, Key Replace Template, and Key_Remove_Template with ytt, focusing on the overlay annotations and the client condition shown in the issue. Compare the rendered YAML for local_client and other clients, then determine whether one configuration can produce the requested rename and removal behavior. Done means the conditional outputs match the described result.
