feat(supportbundle): support secret/... redactor URIs

[xavpaice]

Summary

Adds support for secret/... URIs to LoadRedactorSpec, matching the existing support in LoadSupportBundleSpec.

Changes

• pkg/supportbundle/load.go: LoadRedactorSpec now accepts secret/<namespace>/<secret-name>[/<data-key>] URIs, with a default data key of redactor-spec.
• pkg/supportbundle/load.go: added a package-level loadFromSecret hook so the new code path can be unit-tested without requiring a cluster.
• pkg/supportbundle/load_test.go: added TestLoadRedactorSpec covering default and custom data keys, as well as validation for too few/too many path components.

Motivation

KOTS stores rendered redactor specs in Kubernetes ConfigMaps today and passes configmap/... URIs to kubectl support-bundle --redactors=.... To move those redactor specs to Secrets, the Troubleshoot library and CLI need to be able to load redactor specs from secret/... URIs.
