[ATFT] Add TEST_MODE and PROVISION_STEPS to config.
Include TEST_MODE option and PROVISION_STEPS in the configuration
file. These two are optional arguments. TEST_MODE is set to false
by default. If TEST_MODE is set to true, no prerequisite step check
would be done, user could do the provision step by any order. User
could also modify PROVISION_STEP to change the provision steps that
would be executed in the auto provisioning mode.
