enhancements to support postgres client-cert authentication (#47)

This PR adds a few new chart features which adds to the flexibility of the chart.

- allow extra volumes to be mounted (such as secrets): 2f862c5a48
- pass environment variables also to the init-container: 7044049478
- allow a preparation script to be "injected" into the init-container: 6125a69345

As a concrete example of how this can be used, I use is to configure Gitea to use client certificate authentication against an external Postgres database. That could be accomplished by having a `gitea-postgres-ssl` secret:

```
apiVersion: v1
kind: Secret
type: Opaque
metadata:
  name: gitea-postgres-ssl
data:
  postgresql.crt: <base64...>
  postgresql.key: <base64...>
  root.crt: <base64...>
```

and then mounting this as a volume in Gitea using:

```
extraVolumes:
- name: postgres-ssl-vol
  secret:
    secretName: gitea-postgres-ssl

extraVolumeMounts:
- name: postgres-ssl-vol
  readOnly: true
  mountPath: "/pg-ssl"
```

To get the right permissions on the credentials, we'd use the `initPreScript`:

```
initPreScript: |
  # copy postgres client and CA cert from mount and
  # give proper permissions
  mkdir -p /data/git/.postgresql
  cp /pg-ssl/* /data/git/.postgresql/
  chown -R git:git /data/git/.postgresql/
  chmod 400 /data/git/.postgresql/postgresql.key
```

and to make sure that Gitea uses the certificate we need to pass the proper postgres environment variables (both to the init container and the "main" container):

```
statefulset:
  env:
  - name:  "PGSSLCERT"
    value: "/data/git/.postgresql/postgresql.crt"
  - name:  "PGSSLKEY"
    value: "/data/git/.postgresql/postgresql.key"
  - name:  "PGSSLROOTCERT"
    value: "/data/git/.postgresql/root.crt"
```
