[Bug] Intermittent network connections can create high cpu-use situations for desktop applications.

[REQUIRED] Please fill in the following fields:

• Pre-built SDK
• Firebase C++ SDK version: 11.6.0
• Problematic Firebase Component: Auth
• Other Firebase Components in use: Database/Functions/Storage
• Platform you are using the C++ SDK on: Windows
• Platform you are targeting: Desktop

[REQUIRED] Please describe the issue here:

Intermittent network connections can create high cpu-use situations for desktop applications.

Steps to reproduce:

• Sign into firebase auth.
• Close app.
• Remove internet.
• Open app and instantiate a user.

or

• interrupt internet access.

The following spams the console thousands of times:

INFO: USE_AUTH_EMULATOR not set.
INFO: USE_AUTH_EMULATOR not set.

This creates significant CPU load and overhead when the network connection is lost. I expect the attempt to connect to a live auth instance fails, but there is no rate limit on retries after time 'x', or graceful management of that particular scenario.
