[RFE] Allow helm chart to add extraLabels and extraAnnotations to k8s resources / Set SSL Mode for DB Connection

[jescarri]

Current situation

The helm chart does not allow adding extra labels to the resources it creates, in our clusters we have admission control and we require all resources to be labelled.

DB Connection SSL mode is hardcoded to disabled.

Impact

Helm chart cannot be used if extra labels are required.

Using a database with SSL enabled is not possible.

Ideal future situation

Users can specify a set of extra labels and annotations and configure SSL for the DB Connection.

Implementation options

Add the option in the helm charts.
