Cleaning scripts management

[LaRiffle]

We would like to append scripts to clean the data that we import from other databases

Scripts are stored in a specific registry: https://github.com/arkhn/cleaning-scripts

• [ ] Deploy the cleaning script flask server on scaleway
• [x] Get access to those scripts and load the function name + docstring as a short description
• [x] Display a list of script and allow selecting one
• [x] Add a search functionality to better select the script
• [ ] Configure CLEANING_SCRIPTS_URI env variable to target cleaning script flask server
• [ ] Add a button to request a new script which creates an issue to https://github.com/arkhn/cleaning-scripts or redirect there
