lab tweak, one auth client, Fixes AB#3447250

[fadidurah]

Only need one auth client. Having a second one referencing BuildConfigs will cause issues if the build configs are not passed at library build time.

Pull request overview

This PR consolidates authentication client usage in the Lab API utilities to avoid BuildConfig dependencies at library build time. The change removes a dedicated KeyVault authentication client and extends the existing authentication client to support custom scopes dynamically.

• Removed the separate mLabApiAuthenticationClientForKeyVault field that required BuildConfig at construction time
• Added getAccessTokenForCustomScope() method to dynamically request tokens with custom scopes
• Updated getKeyVaultSecret() to use the single authentication client with a custom scope parameter

private final String mScope;

let's get of rid of this and corresponding constructor. there's only one other caller of the constructor, which can use your new method.

This will clean up the class and your change.

I think we can remove mScope (and ability to pass it through constructor), and just have a default scope field for anyone using getAccessToken().
