Installation Id in `AzureRmContextSettings.json` cannot keep the same with AZ CLI under specific situations

[NoriZC]

Description

Background

After Installing Azure PowerShell, during the first time importing Az.Accounts, we will generate a file called AzureRmContextSettings.json.

For the InstallationId session in this file, we follow the rules:

• If detected azconfig.json generated by AzCLI Installation id, reuse it.
• If not detected, randomly generate a new guid.

By doing so, we can identify the Machines calling AzCLI/ AzPS command by the installation Id.

Issue

But we have some troubles while trying reusing this id. The Installation Id cannot keep the same with AZ CLI under situations when:

• Under case-sensitive systems, like Lunix/ MacOS.

• User defined a AZURE_CONFIG_DIR while installing AzCLI (*).

  (*) How AzCLI generate an Installation Id:

  • It first checks if the environment variable AZURE_CONFIG_DIR is set.
  • If AZURE_CONFIG_DIR is not set, it defaults to ~/.azure/.

Proposed implementation:

1. Handle casing difference
2. Leverage same env var when decting installion id
