Since our version of Chromium is also pinned, a new ChromeDriver (that
drops support for our Chromium version) can cause random (and unrelated
to the corresponding changes) errors on CI.
This commit pins the version of ChromeDriver and it should now be
manually upgraded to a vrsion that is compatible with th currently used
Chromium version.

There are now 3 modes for deployment: next, stable, archive.
We compute which mode (and other deployment properties)
from the `TRAVIS_BRANCH` and the `STABLE_BRANCH`.
If the TRAVIS_BRANCH is master we deploy as "next".
If the `TRAVIS_BRANCH` matches the `STABLE_BRANCH` we deploy as "stable".
Otherwise if the branch has a major version lower than the stable version
and its minor version is highest of similar branches we deploy as "archive".
For "archive" deployments we compute the firebase project and deployment
url based on the major version of the `TRAVIS_BRANCH`.
As well as choosing where to deploy the build, we also use this
to select the environment file for the AIO Angular app.
This will enable the app to change its rendering and behaviour
based on its mode.

(Coincidentally), this wasn't an issue before fdfeaaf1f, because
pre-verification was run after `test.sh`, during which `aio-builds-setup` was
built.
Now that `deploy-staging.sh` is being run before `test.sh`, we need to build
the `aio-builds-setup` scripts first.
