Revision of cost sliders queries necessary

[kaskranenburgQ]

At the moment, the cost sliders are structured in a hard coded manner. Here is an example of the query behind the slider "Investment costs coal plants":

It would be more future-proof to rewrite these slider queries in a structure using a filter so that new or changed nodes names are implemented automatically.

As discussed with @mabijkerk:

Ultimate goal is to have only a few general queries that will set certain groups / collection of nodes / etc., these queries can then subsequently be used in other queries that will be written in a more robust manner. This way, when making changes in projects these general queries should be checked properly (e.g. by using mechanical turk tests). When these queries are correct, then the chance of other queries to be incorrect will decrease significantly. Ultimate result: more robust, less error sensitive.

Options could be to make use of groups and filters:

• for instance costs of CCS power plants: use costs groups and CCS_investment
• for instance costs of coal power plants: use costs groups and some filter to only include coal power plants (based on coal input or some pre-defined categorisation of coal power plants)

We can start with trying out what works best for certain cost queries. In the future, improve robustness of other queries in a similar manner.
