Investigate/Remove usage of sync WebDriver APIs #50144
Description
The flutter_driver web implementation currently relies on sync sockets: https://github.com/flutter/flutter/blob/master/packages/flutter_driver/lib/src/driver/web_driver.dart#L12
We probably shouldn't be using these, since it can hang the tool or test script to block on a socket connection. It seems like the async versions of web_driver incur additional overhead on closing, but that could be investigated as a bug on its own.
- @angjieli did you ever discover the reason for the 15 second delay?

It seems like async web_driver uses HttpClient which has a property called idleTimeout defaults to 15 seconds.

Other than the issue mentioned above, using the async webdriver is more likely to break for non-Chrome driver when calling fromExistingSession() while working perfectly fine with sync webdriver.
