Fix command execution delay of WebDriver for .NET Core 2.0

[YevgeniyShunevych]

There is a bug in Selenium.WebDriver v3.6.0 for .NET Core 2.0: each WebDriver request takes extra 1 second. It reproduces for Chrome, Firefox, etc.

Link to the bug: https://github.com/dotnet/corefx/issues/24104.

Fix

Add method to DriverAtataContextBuilder<TBuilder>:

public TBuilder WithFixOfCommandExecutionDelay();

The fix does: finds HttpCommandExecutor instance of RemoteWebDriver instance and updates its remoteServerUri field by replacing "locahost" with "127.0.0.1".

Usage

AtataContext.Configure().
    UseChrome().
        WithFixOfCommandExecutionDelay().
