Create AKVs as part of bootstrap script

[promisinganuj]

For secure data processing, Fabric notebooks/pipelines should be using Azure Key Vaults (AKV) for storing secrets and secured variables.

This task is to include the creation of AKVs per environment, as part of bootstrap process. i.e., there would be 3 key vaults deployed by default for DEV, UAT, and PROD environments.

Scope:

• Add bicep script to create 3 Azure Key Vaults (AKV), one per environment.
• As part of deployment, save relevant variables as secrets in the respective AKVs. The variable list is yet to be discussed.
• Create a new notebook or update an existing one to showcase how AVK can be used in notebooks and data pipelines.
