Remove implicit config options from provision_devices

Remove implicit config options from provision_devices

Build bot recipes have been upgraded to explicitly request the provisioning
options they need.

At this point it should be safe to remove the code that guessed the required
configuration from the bot name.

Are we sure that all of the requisite bot changes have been made?

Promise to wait for this one until tomorrow morning (my time). I did my best
efforts to check no requisite changes are missing. Also, this time the change
should be easier as it only involves adding extra options to the perf bots (and
no changes to the much larger set of non-perf bots).
