Add computer readable list with framework meta-data

[PGijsbers]

Useful meta-data to collect:

• which task types the frameworks support
• what data types the frameworks support (string, timestamp, missing values, ...)

It allows one to automatically select all frameworks compatible with a benchmark, which also makes it easier/clearer to support frameworks which do not implement all data/task types. Additionally we can make integration of the automl system with the benchmark framework easier if we can automatically determine whether or not to do missing value imputation or other preprocessing.

The only sensible place (to me) to add this seems the frameworks.yaml, as the same framework may have different levels of support in different versions.
