The nova solver scheduler was designed to be a drop-in patch for nova, and it
uses 'nova' as the directory now, however it's easier to manage the project
as an individual python package, therefore we want to move the top directory
out to a separate one, which is called 'nova_solverscheduler'. This patch
will modify the module import dependencies and also add necessary init files
so as to turn the project into a complete python package.
