Make angular component entity-list generic

[tschaffter]

This component developed by Stanley currently only supports the listing or Insight and Resource. By making this component generic, we can then use it to list Resources, Insights but also Projects.

EDIT: The motivation is to add filters to entity-list such as filter by entity (sub)type, createdAt and search field, for example. These filters will then be automatically available on the page that list Resources, Insights, Projects, etc. This brings consistency to the app too.

[tschaffter]

The query emitted to the component that includes entity-list now looks like:

{resourceType: "Dashboard", orderedBy: "metadata_created desc"}

Next: Set the type of the emitter, thought the query object returned doesn't always have the same keys (here resourceType).
