Create lava_common for Timeout and Exceptions

Make a clear separation between lava_server and lava_dispatcher
binary packages so that a master does not need all the dependencies
of lava-dispatcher installed (and does not necessarily have a
local worker).
Update documentation on how lava-common can be used.
