core: Add support for reader/query plugins.
A reader plugin can be used to query a data-store based on a query described
by an AST. The plugin module provides a generic function for this purpose.
At the moment, only a single reader plugin can be used at a time. Supporting
multiple readers requires a good merge strategy. The challenge is to handle
filters and query conditions correctly which may evaluate differently after
two stores have been merged.
