Change apiTimeout type to Optional

To keep backward compatibility with updates/upgrades of
existing env, this parameter can not be type Required.

Error msg on update env:

message: 'error validating existing CRs against new CRD''s schema for "openstackcontrolplanes.core.openstack.org":                       error validating core.openstack.org/v1beta1, Kind=OpenStackControlPlane "openstack/controlplane":
    updated validation is too restrictive: [].spec.octavia.template.apiTimeout: Required
    value'
