Refactor wipe option to wipe on default and have option to skip wipe.

Also remove the option -w to only wipe without provisioning. This was temporary
functionality to recover from INSUFFICIENT_STORAGE on device error. With the
default wiping, this should be unnecessary. For bots that skip wiping, we can
still manually fix by manually running without --skip-wipe.
