As a part of this task, we will remove the environment variable completely from the .NET SDK ecosystem.Create a new Environment Variable to externalize circuit breaker timeout counter reset window: Goal is to create a new environment variable
AZURE_COSMOS_PPCB_TIMEOUT_COUNTER_RESET_WINDOW_IN_MINUTESto externalize the PPCB timeout counter reset window. The default value for this would be5minutes.Add New Internal Client Options to disable PPAF: Add a new internal cosmos client options to disable PPAF explicitly. Once set, this will be used to disable PPAF irrespective of the account settings.
