Include Namespace Support for InfluxDB 2 Helm Chart

**Description**:
Hello,

I have been working with the InfluxDB 2 Helm chart and noticed that it currently lacks support for specifying a namespace. I believe adding this feature would greatly enhance the flexibility and usability of the Helm chart.

**Proposal**:
I propose adding the following configuration option to the InfluxDB 2 Helm chart:

```yaml
namespace: {{ .Release.Namespace | quote }}
```
This would allow users to easily deploy InfluxDB 2 into the desired namespace, aligning with the practices of other Helm charts such as Kafka and Postgres.

**Examples**:
Here are some examples from other Helm charts that demonstrate the use of a namespace parameter:

- Kafka: [bitnami/kafka/templates/broker/statefulset.yaml](https://github.com/bitnami/charts/blob/main/bitnami/kafka/templates/broker/statefulset.yaml#L12C1-L12C1)
- Postgres: [bitnami/postgresql/templates/serviceaccount.yaml](https://github.com/bitnami/charts/blob/main/bitnami/postgresql/templates/serviceaccount.yaml)

**How I Can Help**:
I would be glad to assist with the implementation process.

Thank you for considering this proposal. I look forward to contributing to the InfluxDB 2 Helm chart and improving the user experience.

Best regards,
Tomas

Start by locating the InfluxDB 2 Helm chart templates and compare their namespace handling with the referenced Kafka broker StatefulSet and PostgreSQL ServiceAccount templates. Render the chart with a chosen release namespace and verify that the generated Kubernetes resources use the requested namespace consistently.
