* test: add redis restart test back to traefik2 suite
* refactor(suites): mustpress -> mustinput for totp
* refactor(suites): rename suites for test ordering
* 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.
* [FEATURE] Autofocus on authentication and OTP pages
This change sets the input focus on the first factor authentication and OTP pages.
The behaviour for the first factor authentication page has also been amended slightly, if an incorrect username or password is provided the password field will be cleared and set as the focus.
One thing to note is that the OTP page does not focus on any re-rendering and this is because the component doesn't handle focusing. This means that the OTP input only is auto-focused when you first visit it, if you enter an incorrect OTP there will be no focus.
Ideally we should be looking for a different library or writing a component for this ourselves in future.
Closes#511.
* Add TODO markers for potential refactor
