More APIs for StackConfigPolicy

[thbkrkr]

Adds support for more APIs to the StackConfigPolicy custom resource:

• Ingest pipelines (/_ingest/pipeline)
• Index Lifecycle Policies (/_ilm/policy)
• Index templates (/_index_template)
• Components templates (/_component_template)
• Security Role mappings (/_security/role_mapping)

Additional things:

• remove managed labels if they are no longer defined when reconciling file settings Secret
• fix case 'Settings secret must be updated to reflect the policy settings' in controller_test.go

---

For testing (here is a manifest with all settings):

kubectl apply -f https://gist.githubusercontent.com/thbkrkr/70bf369e648218e477b2252f83e00ef7/raw/367833447d2d14ee9619045434a82a156d6bb4b5/stackconfigpolicy_all-settings.yaml

/_cluster/state | jq '.metadata.reserved_state' should return all configured settings:

{"file_settings":{"version":1669732664259516200,"handlers":"cluster_settings":{"keys":["indices.recovery.max_bytes_per_sec"]},"ilm":{"keys":["ilm_test"]},"index_templates":{"keys":["component_template:component_template_test","component_template:runtime_component_template_test","composable_index_template:template_test"]},"ingest_pipelines":{"keys":["pipeline_test"]},"role_mappings":{"keys":["role_test"]},"slm":{"keys":["slm_test"]},"snapshot_repositories":{"keys":["repo_test"]}},"errors":null}}

kubectl delete scp config-policy

/_cluster/state | jq '.metadata.reserved_state' should return no configured settings:

{"file_settings":{"version":1669733827130773500,"handlers":{"cluster_settings":{"keys":[]},"ilm":{"keys":[]},"index_templates":{"keys":[]},"ingest_pipelines":{"keys":[]},"role_mappings":{"keys":[]},"slm":{"keys":[]},"snapshot_repositories":{"keys":[]}},"errors":null}}

LGTM. I have not tested it yet. Do we plan to make an exception to the feature freeze for 2.6?
