Support ASF to retrieve EO data, mainly SAR one.

• A python package is available for this provider https://github.com/asfadmin/Discovery-asf_search under BSD-3-Clause license (compatible with eodag). pypi: https://pypi.org/project/asf-search/ conda-forge: https://anaconda.org/conda-forge/asf_search Documentation: https://docs.asf.alaska.edu/asf_search/basics/

• A python api plugin will be preferred (faster development time and easier maintainability), but API is also documented:

API documentation: https://docs.asf.alaska.edu/api/basics/ search example: https://api.daac.asf.alaska.edu/services/search/param?intersectsWith=POLYGON((-2.671%2042.2314,4.3776%2042.2314,4.3776%2045.9707,-2.671%2045.9707,-2.671%2042.2314))&platform=SENTINEL-1&instrument=C-SAR&start=2020-05-02T22:00:00Z&end=2020-05-20T21:59:59Z&maxResults=250&output=jsonlite2

Hi @ahuarte47 , as you can see its priority is quite low in the features requests backlog.

I took a look at it and update the feature-request description. It might be not so difficult and fast to implement it using asf-search through a new eodag api plugin. If you or someone else would like to submit a Pull Request for it, we can of course provide support and advice for the development and configuration

Thanks @sbrunato for the info.
