Better management of storage size (disk full)

[pl-buiquang]

Sometimes when importing a new output this fails because the device is full.

For that:

• we should keep a minimum temp space available (limit number of new studies for instance) for input import / export / ...
• queue import jobs when temp space is full (awaiting it to be free again) since it's temporary

Context:

The disk applis/antares/data/tmp should be monitored. It should be at least 200 GB free. The size of a study is less than 500 MB. The result of a study can reach some GB. They are retrieved from CALIN.

For example, in the run_study function, the task should be put on hold if the disk space is insufficient.

In Elastic Search, the disk space is indicated in log files.
