[Feature request] Add drop strategy

[sathieu]

I want a strategy to remove a key in a map completely.

My usecase it to remove annotations app.quarkus.io/build-timestamp andapp.quarkus.io/quarkus-version from:

metadata:
  annotations: 
    app.quarkus.io/build-timestamp: 2025-02-18 - 15:18:03 +0000
    app.quarkus.io/quarkus-version: 3.15.3
    app.quarkus.io/vcs-uri: https://github.com/keycloak/keycloak.git

(ref)

To have the following result:

 metadata:
   annotations: 
-    app.quarkus.io/build-timestamp: 2025-02-18 - 15:18:03 +0000
-    app.quarkus.io/quarkus-version: 3.15.3
     app.quarkus.io/vcs-uri: https://github.com/keycloak/keycloak.git
