Previously the setup-rbe.sh script did not allow accounts that did
have domains of angular.io or google.com. Since we add emails from
other domains into everyone@angular.io, we are unable to be certain
in the script that the account is not actually a member of the
required group. This change adds the option to choose to continue
with an email account logged in which we cannot verify by domain.

We have determined that the upload time cost of remote caching via http is too costly
to be effective for our distributed usage scenario. However this cost is still worth
it for us for Windows CI runs on a full cache hit move from a ~60 minute task to ~10
minutes.
It is worth noting that this remote http-caching is entirely separate from RBE caching
mechanisms.
