Create a secret for GCP experiments

You must create a service account to derive the authentication secret to run experiments on GCP.

To create the service account and secret:

Set your current project. Replace <project-id> with your project ID:
```
gcloud config set project <project-id>
```
Create a new service account. Replace <service-account-name> with the name you want to give to the service account:
```
gcloud iam service-accounts create <service-account-name>
```

After the service account is created, you can generate a new JSON key file. Replace <service-account-name> with the name of your service account and <key-file> with the path where you want to save the key file:

gcloud iam service-accounts keys create <key-file> \
--iam-account <service-account-name>@<project-id>.iam.gserviceaccount.com

The generated JSON key file will contain the fields you mentioned, and it looks something like this:

{
    "type": "service_account",
    "project_id": "<project-id>",
    "private_key_id": "<private-key-id>",
    "private_key": "<private-key>",
    "client_email": "<service-account-name>@<project-id>.iam.gserviceaccount.com",
    "client_id": "<client-id>",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://oauth2.googleapis.com/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/<service-account-name>%40<project-id>.iam.gserviceaccount.com"
}

Prepare the secret YAML based on this JSON:

apiVersion: v1
kind: Secret
metadata:
  name: cloud-secret
type: Opaque
stringData:
  type: "<type>"
  project_id: "<project-id>"
  private_key_id: "<private-key-id>"
  private_key: <private-key>
  client_email: "<client-email>"
  client_id: "<client-id>"
  auth_uri: "<auth-uri>"
  token_uri: "<token-uri>"
  auth_provider_x509_cert_url: "<auth-provider-x509-cert-url>"
  client_x509_cert_url: "<client-x509-cert-url>"

caution

Newline (\n) characters within the private key are crucial. Avoid using double quotes to prevent their loss.

Create the secret YAML file in the chaos infra namespace using the command:
```
kubectl apply -f secret.yaml -n <CHAOS-NAMESPACE>
```
