feat: Kustomize ignore components - issues/18634

[bradkwadsworth]

Added ability to ignore Kustomize component directory if it does not exist. A new field called ignoreMissingComponents, if enabled, will verify if a given components directory exists and if not will log a debug message. Only found component directories will be used if ignoreMissingComponents is set to true.

Fixes #18634
