- when instantiating a datasource, the datasource service checks if the
plugin module exports Explore components, and if so, attaches them to
the datasource
- Explore component makes all major internal pluggable from a datasource
`exploreComponents` property

it as an exported Explore component
- Added new Start page for Explore, also exported from the datasource
