Support NoInternetBrowserFactory and describe setup instructions for local environment without internet access / Custom browsers like Yandex

[mialeska]

Instruction example in case of our SpecFlow-based template:

1. Add CustomBrowserFactory
2. Add respective nuget package of driver e.g. Selenium.WebDriver.ChromeDriver
3. Add hook to be executed before tests:
   [BeforeTestRun(Order = 0)]
   public static void ConfigureBrowserFactory()
   {
   AqualityServices.BrowserFactory = new CustomBrowserFactory(
   AqualityServices.Get(),
   AqualityServices.Get(),
   AqualityServices.Get(),
   AqualityServices.LocalizedLogger);
   }

Example of CustomBrowserFactory was in tests for usecases
https://github.com/aquality-automation/aquality-selenium-dotnet/blob/master/Aquality.Selenium/tests/Aquality.Selenium.Tests/Integration/Usecases/CustomBrowserFactoryTests.cs
, but could look like that:

using Aquality.Selenium.Configurations;
using Aquality.Selenium.Core.Localization;
using Aquality.Selenium.Core.Utilities;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.IE;
using OpenQA.Selenium.Remote;
using System;
using System.IO;
using System.Reflection;
