Survey of the group of federated service providers

[almereyda]

In libresh/awesome-librehosters#7 we understood that we need a structured survey of the otherwise lossely collected librehosters group of groups. The textual form seems insufficient to conduct a strategic fact collection to map out the field.

That issue holds precious ideas on modelling questions, that may be of use here.

Further approaches are listed in https://github.com/libresh/catalogue#application-solutions

Following on with this aids the overall understanding of possible cooperation vectors within the assumed https://framagit.org/librehosters federation.

This issue narrows the scope of the loosely specified #6.
