executionDuration not respected for certain output formats

[almicol]

Hi Grégory, Depending on the output format selected, a job could still run after having reached the executionDuration limit. This can cause stress to the database server, hence we are going to disable the following formats until a fix is implemented: csv, tsv, text, html, json

Formats which do respect the executionDuration limits are: votable, votable/b, fits

PS: Other formats were not tested.
