feat: multiple users per alias

 The URL, driversPath, usernames, passwords, and application user details will be set from environment variable (if found). Otherwise, the value from the config file will be used. The browserOptions node supports anything in the EasyRepro `BrowserOptions` class.
 
+Tests will be distributed evenly between the users if multiple users are configured with the same alias. This can be helpful when you run a large number of tests in parallel and are encountering errors due to user-level platform API limits.
+
 #### User profiles
 
 Setting the `useProfiles` property to true causes the solution to create and use a unique [profile](https://support.google.com/chrome/answer/2364824?co=GENIE.Platform%3DDesktop&hl=en) for each user listed in the config file. This currently only works in Chrome & Firefox and attempting to use it with Edge or IE will cause an exception to be thrown. By using profiles test runs for the same user will not be required to re-authenticate, this saves time during test runs. [To take full advantage of this you will need to have the "Stay Signed In" prompt enabled.](https://docs.microsoft.com/en-us/azure/active-directory/fundamentals/keep-me-signed-in)
