Simplify deployment instructions in README (#324)

Browse Source 
Fixes #287

### Motivation

The current steps to install the Apache Pulsar Helm Chart include an unnecessary script `scripts/pulsar/prepare_helm_release.sh`. It relies on tooling that has not been maintained and is not a part of the Apache Pulsar project. As such, I propose we remove these references.

Note that one of the reasons we used these scripts historically is to simplify deployment. Without these scripts, we should document what is necessary. I am tracking that work here https://github.com/apache/pulsar-helm-chart/issues/323.

## Deploy Pulsar to Kubernetes ## Deploy Pulsar to Kubernetes
1. Clone the Pulsar Helm charts repository. 1. Configure your values file. The best way to know which values are available is to read the [values.yaml](./charts/pulsar/values.yaml).
2. Install the chart:
```bash ```bash
git clone https://github.com/apache/pulsar-helm-chart helm install <release-name> -n <namespace> -f your-values.yaml apache/pulsar
```
```bash
cd pulsar-helm-chart
``` ```
2. Run `prepare_helm_release.sh` to create required kubernetes resources for installing this Helm chart. 3. Access the Pulsar cluster
- A k8s namespace for installing the Pulsar release (if `-c` is specified)
- Create the JWT secret keys and tokens for three superusers: `broker-admin`, `proxy-admin`, and `admin`.
By default, it generates asymmetric pubic/private key pair. You can choose to generate symmetric secret key
by specifying `--symmetric` in the following command.
- `proxy-admin` role is used for proxies to communicate to brokers.
- `broker-admin` role is used for inter-broker communications.
- `admin` role is used by the admin tools.
```bash
./scripts/pulsar/prepare_helm_release.sh -n <k8s-namespace> -k <pulsar-release-name> -c
```
3. Use the Pulsar Helm charts to install Apache Pulsar.
This command installs and starts Apache Pulsar.
```bash
$ helm install <pulsar-release-name> apache/pulsar
```
5. Access the Pulsar cluster
The default values will create a `ClusterIP` for the proxy you can use to interact with the cluster. To find the IP address of proxy use: The default values will create a `ClusterIP` for the proxy you can use to interact with the cluster. To find the IP address of proxy use:
