Implement "ground-truth" check for proctoring to make sure that we are sending pictures

When more than 10 times the expected maximum proctoring interval has pasased without any picture being successfully sent to the server, the proctored session will be aborted.

Various changes on the proctoring artifacts users list:

- display some statistics on the collected artifacts for each user: count, number of reviewed, number of flagged, plus a colored progress bar indicating the review status, orange when in progress, red when completed with flags and green when everything is ok

- switched to a template::list to avoid too much handcrafting

- removed the red delete button from the top of the page, redundant, since we have the bulk actions on the list

- refined the behavior of the bulk-action delete button: it will be disabled when nothing is selected

- now we always trigger a reload when new artifacts are received for this object, but we cap it to 60 seconds

Provide an own translation for "All" that considers the specific item (e.g. for gendering)

Significant improvements on the proctoring display UI to help the review process of proctored artifacts:

- user can flag artifacts as OK or to be reviewed

- user can add and delete comments on the single artifacts

- user can filter artifacts by "verified/not verified" "flagged/not flagged" and "all". A counter is displayed showing how many over the total number are being displayed

- interface will update as before when new pictures come in from an ongoing exam

- interface has been designed "mobile first" and with minimal, mostly graphical dependencies, to Bootstrap

Introduce a data model for "proctoring artifacts", aka the pictures

and audios, which so far have only lived as files in the filesystem

named after a convention

The new datamodel allows to quickly and reliably retrieve the pictures

collected by proctoring and also provides for a technical space, in

form of a JSON metadata column, to store additional information coming

from e.g. postprocessing phases.

The idea is to use this feature to provide reviewing tools of proctoring results and allow for flexile downstream postprocessing.

The file naming convention has not been changed for the time being, so this would be

retro-compatible. However, integrators should start relying on the new

data model to retrieve pictures.

Proctoring enforcing reform:

so far, to proctor applications that do not have a "single point of entry", such as e.g. dotlrn communities, we have integrated the lib/proctoring-enforce include into the website master template. Now we improve from this by introducing a callback mechanism that allows the single packages to decide if a request is "theirs to be proctored" or not.

Safe Exam Browser support reform:

- capture both RequestHash and ConfigKeyHash from the request headers and use both to validate the request. This enables to choose to just enforce the plain conf, instead of the whole conf+binaries combination, which is platform-specific

- support storing multiple keys, required e.g. to support multiple platform-specific keys

- make suppling of the config file optional

- extend automated tests to cover new features

- clanup redundant index

- return config file using its stored filename

Correct hash challenging:

actually, the hash sent by the browser changes based on the requested URL, so it does not make sense to set it directly.

  1. … 2 more files in changeset.
Basic backend support for Safe Exam Browser (https://safeexambrowser.org/):

via the API is possible to associate a Safe Exam Browser configuration and its validation key to

the proctored object. The proctored page will then take care of enforcing that, if the safe exam

browser is in use, the supplied request header matches with the configuration and the URL.

When such match fails, we now return the configuration file to the browser, so that users can

open it and restart their session properly configured.
