Implement page.on('console') to be able to assert on logs

[ankur22]

Feature Description

There has been a request to be able to assert on logs. The use case is for when a user want to assert that something has occurred, but that something can only print to the console with console.log, and there is nothing on the site itself that can be used. When something is logged, we should be able to bring that to the attention of the user who can compare it against an expected string.
