This adds POST /candidates/<candid>/<visit>/dicoms to upload a dicom. GET /candidates/<candid>/<visit>/dicoms/<filename>/processes to get the server processes related to that dicom upload (mri_upload) POST /candidates/<candid>/<visit>/dicoms/<filename>/processes to start a mri_upload server process on that dicom. GET /candidates/<candid>/<visit>/dicoms/<filename>/processes/<processid> to get the state of a process

I am waiting for https://github.com/aces/Loris/pull/6671 to get merged so I can add tests

This needs to go in a 0.0.4-dev, not 0.0.3

@xlecours could you rebase your branch?

[ridz1208]

@xlecours I rebased this for you here https://github.com/ridz1208/Loris/tree/adding_dicom_upload

if you want I can force push to your branch or you can simply pull it and force push it yourself.

@cmadjar @driusan this one is now rebased and seems to be passing tests

[xlecours]

This is missing integration tests. @xlecours

[driusan]

@cmadjar can you review?

[xlecours]

@xlecours If you do the rebase, @cmadjar agreed to review it again. Also, now that we have a testsuite for the api module, you should add some tests.

[driusan]

@xlecours are you referring to yourself in the third person? Who's supposed to be writing tests?
