Is your feature request related to a problem? Please describe.
I need different configurations with different plugins for the same provider. This configuration appears as 2 distinct provider in EODAG.

Describe the solution you'd like
Adding a property group to the provider. So I could have both my configurations sharing the same group and appear to me as a single provider.

Additional context

group is an optional field

Example:

I have 2 provider configuration in EODAG:

• earth_search
• earth_search_cog

I configure both with group earth_search.

• When I list the product types for provider earth_search, EODAG return the merged list of product types from earth_search and earth_search_cog.

• In server mode, the returned product types display earth_search as provider name.

• When I search for products with provider earth_search, EDOAG search on both provider using the existing fallback mechanism. The returned products display earth_search as provider name.

• When I ask for queryables with provider earth_search the response is the intersect of queryables from earth_search and earth_search_cog.

• available_providers returns only one entry for both: earth_search.
