[scalardl-auditor] Support Azure Marketplace

[kota2and3kan]

Description

This PR updates the ScalarDL Auditor Helm Chart to support Azure Marketplace.

To list ScalarDL Auditro on the Azure Marketplace, we have to update our helm chart based on the rules of Azure Marketplace. So, I updated ScalarDL Auditor chart as follows:

• Add global.azure.* in the values.yaml file.
• Update spec.template.spec.containers[].image in the deployment.yaml file to pull the container image from ACR for Azure Marketplace.
• Add the azure-extensions-usage-release-identifier label in the deployment.yaml to trace pods and charge license fees by Azure.

You can see what we need to list products on the Azure Marketplace in the following Azure document.

• Update the Helm chart
• Make updates based on your billing model

Also, to reduce the maintenance cost (avoid duplicated maintenance), I updated the current helm chart instead of creating the Azure Marketplace dedicated helm chart. To achieve that, I added the following things:

• Add global.platform in the values.yaml file.
  • I assume this parameter for switching our helm chart based on platforms (to list on each cloud marketplace, partner catalog or something like that) in the future. In other words, this configuration is not related to Azure Marketplace directly.
  • For example, if you set global.platform=azure, ScalarDL Auditor chart use or add the Azure Marketplace dedicated configurations.
  • We need to do the same thing in the Envoy chart (subchart of ScalarDL Auditor chart). So, I decided to add this parameter as Global Values. We can use this global.platform configuration in both ScalarDL Auditor chart (main chart) and Envoy chart (subchart).

Please take a look!
