Support for deployment in Azure Government Cloud (Leonardo)

[bennettn4]

Part of large effort to add support for services to run in Azure Government cloud.

Two parts:

1. Support for government cloud curls

• Added environment variable for AZURE_ENVIRONMENT
• Updated azure-vm-init script to support gov suffix

2. Fixes for running Leo in Azure. The user pet token is unavailable in Azure so calls which used it for Leo->WSM were replaced with the Leo service account token, and appropriate permissions to the workspace were given to the Leo service account.
