Error writing search results to GeoJson using eodag-sentinelsat provider

[ahuarte47]

Serialization of search results does not take care of Date/Datetime objects in metadata of Products fetched.
It might be an edge case but it might be interesting to fix it.

Error
TypeError: Object of type datetime is not JSON serializable

Install sentinelsat plugin

python -m pip install eodag
python -m pip install eodag-sentinelsat

Configure 'scihub' provider with highest priority.

Code To Reproduce
CLI command:

eodag -vvv search --conf "eodag-user_conf.yml" --box .... --all --storage "my_search.geojson"

Output

Environment:

• Python version: 3.7.4 on Windows 10
• EODAG version: 2.2.0

Additional context:
Using CS-SI/eodag#235 to configure the settings of this provider in an user configuration file.

Fix in my own code:

Thanks for pointing out this issue.
The problem is that eodag-sentinelsat uses datetime objects to store date metadata. We must use ISO-8601 str like for other providers instead

Thank you very much to everyone!
