[autoroll] Rename CrOS autorollers and the profile they roll to

As detailed in crbug.com/1135245, we need to rename CrOS profiles.
As one of the last steps, we need to rename the autorollers and
the underlying profiles they roll to. The good news is that we
can reduce the number of rollers from 3 to 2. But we can only do
this for canary branch, and propagate to release branches on each
branch point.
