* 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.
* Encode URL set to rd parameter.
URL encoding that parameter solves PR #476.
Some URL parameters set during redirection were magically disappearing
after the redirection due to the authentication process. By using URL encoding,
those parameters should not be stripped anymore.
* Fix integration tests.
