Allow to search/filter contracts

[marien-probesys]

Problem

The list of contracts is quite difficult to browse when there are many contracts.

Solution

Provide a search engine for the contracts to filter by:

• name
• status (status:coming, or status:ongoing, or status:finished)
• organization (org:"org name" or org:#id)
• alert statuses (has:alert, or alert:consumption, or alert:date)

For now, we're just going to provide an advanced form to avoid the complexity of a quick search form.
