Explicitly differentiate "analysis" Tools from "benchmarking" Tools

[lcodo]

In Tool, add a property defining whether the tool corresponds to a benchmarking metrics implementation. If so, further specify the type of implementation: "validation block", "metrics block", "aggregation block", "benchmarking workflow"

[jlgelpi]

Perhaps do it in a single property tool_type with options: "participant", "bench_validation","bench_metrics",.... or more appropriate names,

[jmfernandez]

We should think on a more appropriate way to annotate the functionality of the tool, which is something which already happens at bio.tools . So, postponing to later
