Alternator's user managed serving certificate is not supported

[rzetelskik]

I've noticed that although our API has an option for user managed serving certificate for alternator

scylla-operator/pkg/api/scylla/v1/types_cluster.go

Line 570 in 59f6593

UserManagedOptions *UserManagedTLSCertificateOptions `json:"userManagedOptions,omitempty"`

, the certs are only set up for operator managed type:

scylla-operator/pkg/controller/scylladbdatacenter/sync_certs.go

Line 408 in 59f6593

if sdc.Spec.ScyllaDB.AlternatorOptions != nil &&

scylla-operator/pkg/controller/scylladbdatacenter/resource.go

Line 564 in 59f6593

if sdc.Spec.ScyllaDB.AlternatorOptions != nil {

We should set up certificate generation for user managed type as well.

We should set up certificate generation for user managed type as well.

User managed kind of means we don't generate the certs but only configure the given one.

but only configure the given one

which we don't, although yes, it manifests in resource creation, not in cert generation

which we don't

I guess it works with the same name only today but we should fix plumbing it through
