Option to configure Web API parameters as path params

[alexdma]

It would be nice to be able to choose whether a parameter that maps to a SPARQL variable should be a query param or a path param. For example, one may want to turn:

basil/abcdef1234/api?type={type}&term={term}

into something like

basil/abcdef1234/api/{type}/{term}

This obviously means that the Web API parameters would become positional and there should be a way to configure that. I can think of a few ways:

1. Extend the naming convention with ordering, for example ?_1_type could mean that type is a path parameter that comes before any other.
2. Extend alias definition to support templating, for example if I want to alias abcdef1234 as search I could define the alias as {type}/search/{term}.
3. Infer the order from where the variables first appear in the query (my least-favourite option).
