fix/homogenize external service TLS Secret management

What does this MR do and why?

Persistence of unused files following the !1480 (diffs) merge request.

The existence of these files in the codebase can lead to errors in development and create the impression that certificates are being created, even though this code is no longer in use.

Cleanup is required for some units (harbor, neuvector ...).

find kustomize-units -type f -name "*tls*"

kustomize-units/harbor-init/harbor-tls.yaml
kustomize-units/neuvector-init/neuvector-tls.yaml

Some units does not use tls-components and certificate definition is in the code base:

find kustomize-units -type f -name "*certificate*"

kustomize-units/grafana-init/grafana-certificate.yaml
kustomize-units/keycloak/keycloak-internal-certificate.yaml
kustomize-units/kubevirt-manager/kubevirt-manager-certificate.yaml
kustomize-units/thanos-init/thanos-certificate.yaml
kustomize-units/tls-components/tls-certificate/certificate.yaml
kustomize-units/vault/vault-internal-certificate.yaml
