Proposed changes

This patch will change the current behavior that would default the execution to use devtools as automation engine and instead will setup and run a browser driver. Ultimately we want to deprecate devtools as WebDriver will provide everything needed. The maintenance of the package is not manageable and given all the new features in Bidi there doesn't seem much value to have WebdriverIO users run tests through Puppeteer.
