[Linaro-validation] De-emphasize serial connection for LAVA Dispatcher, introduce LAVA Master Agent, LAVA Test Agent

I've registered another blueprint. This time on LAVA Dispatcher. The goal is similar as the previous blueprint about device manager, to gather feedback and to propose some small steps sub-blueprints that could be scheduled in 2012.04.

The general goal is to improve the way we run tests by making them more reliable and more featureful (richer in state) at the same time.

Please read and comment on the mailing list
