* test: add redis restart test back to traefik2 suite
* refactor(suites): mustpress -> mustinput for totp
* refactor(suites): rename suites for test ordering
Allow users to configure the TOTP Algorithm and Digits. This should be used with caution as many TOTP applications do not support it. Some will also fail to notify the user that there is an issue. i.e. if the algorithm in the QR code is sha512, they continue to generate one time passwords with sha1. In addition this drastically refactors TOTP in general to be more user friendly by not forcing them to register a new device if the administrator changes the period (or algorithm).
Fixes#1226.
* refactor(suites): replace selenium with go-rod
This change replaces [tebeka/selenium](https://github.com/tebeka/selenium) with [go-rod](https://github.com/go-rod/rod).
We no longer have a chromedriver/external driver dependency to utilise Selenium as we instead utilise the Chrome Dev Protocol to communicate with the browser.
Rod [documents](https://go-rod.github.io/#/why-rod) benefits of choosing the library as opposed to the available alternatives.
This PR changes the suites tests so if go test -short is used, they are skipped per go standards and a message is displayed. Additionally removed some redundant types from suite_high_availability_test.go and adjusted a warning about a nil req var.
