Gateway: Adds parallel retry logic to get account information.

Description

This reduces the time to get the account information from over 70 seconds if the primary region gateway is down to a little over 5 seconds if the user has preferred regions configured. The get account information is needed on SDK initialization and on certain failures which requires getting the updated account information to check for failovers.

Current SDK logic
Global Endpoint -> 5 sec
Global Endpoint -> 10 sec
Global Endpoint -> 20 sec
Primary Endpoint (which most of the time is the same as the global endpoint) -> 5 sec
Primary Endpoint -> 10 sec
Primary Endpoint -> 20 sec
Secondary Endpoint -> success

Total time to get the success from the secondary region is over 70 seconds + time for the secondary endpoint to respond

New SDK logic
