[PATCH] Allow the specification of a "mode" property on the LLDB Builder

[Zachary Turner]

Hi gkistanova, rfoos,

The idea is that, if a builder goes red because of a failed atomic operation, we should be able to enter property "mode" with value of "fresh" from the build console and get the build working again without having to log into the machine.
