Rdanzey/helm-fixes-existing-db-secrets (#3033)

Browse source 
Fixes some Helm templating issues when setting up a deployment with an
existing database / signing keys.

- Allows for `.Values.postgresql.enabled: false` as long as
`.Values.global.dendrite_config.database.connection_string` is defined
- Allows for '.Values.signing_key.create: false' if
`.Values.signing_key.existingSecret` is set

Also fixes an error in the template resulting in profiling port not
being set correctly:

```
Error: template: dendrite-meta/charts/dendrite/templates/deployment.yaml:60:35: executing "dendrite-meta/charts/dendrite/templates/deployment.yaml" at <$.Values.global.profiling.port>: nil pointer evaluating interface {}.port
```
