Fix namespace handling and missing dnsNames (#99)

Fixes for wrong namespace handling in some RBAC and missing dnsNames for TLS

### Motivation

Fixes old unused handling of namespace name in RBAC for autorecovery and bookkeeper.
Fixes Helm exception of missing key when not defining TLS dnsNames

### Modifications

Use namespace template in RBAC definitions for bookkeeper and autorecovery. Add if around every `toYaml .Values.tls.bookie.dnsNames` clause in TLS certs definitions.
