Add possibility to customize cert-manager annotations

[ppawlowski]

Description

Currently, the Helm chart only supports the clusterIssuer (cluster-wide issuer) method for certificate manager annotations.
There is a need to support namespace-scoped cert-manager issuer by using following annotations:

cert-manager.io/issuer
cert-manager.io/issuer-kind
cert-manager.io/issuer-group
