We need to actually wait for the "Install" button to be enabled before clicking it otherwise we have a race condition where it sometimes works. Also change the `expect(page.find(...))` to `expect(page).to have_css` as this is prefered to avoid race conditions

Also remove the flakiness by using
`expect(page).to have_css(..., exact_text: '')` instead of
`expect(page.find(...).text).to eq('')` since the former will wait until
the text has this value while the latter will only wait for the element
to exist then test its text straight away which introduces a race
condition if the element is already there with a previous text value.
This test was failing locally most of the time because of this other
way of asserting.

GKE 1.8 has RBAC on by default, since GKE has bumped the default version
to 1.8.7 RBAC is now on, and we don't support that out of the box.

This was also avoiding cluster applications (tiller, prometheus, etc), to
be installed.
