[PATCH 4/8] oeqa/controllers/masterimage: more robust master image startup

Instead of powering up the target when the object is constructed, wait
until deploy is called. Then there are basically two different
scenarios:

a) The device is booted into the master image already, in which case
we can just use it
b) The device is booted into another image or can't be contacted, in
which case we need to power cycle it. Here we also now wait until it
has booted up instead of trying to contact it immediately.
