Breaking Change in 5.1.1 to change default selenium relay protocol to 'https'

[martin770]

A feature was added in protractor 5.1.1 that broke my ability to run tests on sauce labs.

feat(saucelabs): Add Sauce Labs HTTPS Support (#4071) -- commit

Version 5.1.1 added this commit to change the default protocol for the sauce labs selenium relay to 'https' instead of the previous 'http'. This should be pointed out as a breaking change in the changelog.md file.

Version 5.1.2 added the ability to change the protocol via a new configuration option (protractor.conf.js sauceSeleniumUseHttp). This new configuration option should be mentioned in the changelog.

It took me a bit of time to track down the problem as I was upgrading from 4.0.14 to 5.2.0. And in this case, 5.1.1 is completely unusable on sauce labs.
