List pending experiments and displaying currently running experiment in `scheduler.py`

[giwon2004]

Feature you want to implement

Implement a scheduler that shows the list of experiments and their status

How the feature is implemented

In iquip/apps, make a new file named scheduler.py to implement the GUI, using qiwis, according to the python code artiq/artiq/dashboard/schedule.py.

It adds a layout that has QListView for listing pending experiments. (Class ScheduleDock in artiq/artiq/dashboard/schedule.py used QTableView to show information like expid and status in a table, but I want to customize the items inside the list.)

• Here, I want to take advantage of QListView.Movement = QListView.Free to enable changing the priority of experiments in the scheduler GUI. But if this does not work, then I would try hardcoding the drag & drop property later.

An isolated frame (for displaying the current experiment) and this QListView will contain instances of the class ExperimentView, which will be later implemented (mentioned in Discussion#62 and will be implemented through Issue#64).

It looks so cool property! However, I'm worried that changing the priority looks difficult, and I think you should cancel the experiment and re-sumbit it. If you think it would become a big implementation, you can separate into several issues!

Oh, I did not know that changing priorities is a big deal.

If it is, I guess I can implement everything except this drag & drop feature first, and then try it.
