Description

This PR introduces the following changes to simplify the maintenance and use of the envoyextensions/extensioncommon package:

  • Augment the interface for BasicEnvoyExtender to support patching lists of resources.
  • Merge the functionality provided by ListEnvoyExtender into BasicEnvoyExtender
  • Create a new BasicExtensionAdapter struct that provides no-op implementations of all the extender interfaces so extensions need only implement the interfaces they care about.
  • Move some common functions into the resources.go file.
  • Add some new common functions for modifying lists of Envoy filters.

Testing & Reproduction steps

  • Existing Envoy golden tests for the builtin extensions all pass without modification.
  • Unit tests have been added for net-new functionality.

PR Checklist

  • updated test coverage
  • external facing docs updated
  • appropriate backport labels added
  • not a security concern
