build(snap): upgrade kuiper to 1.4.2 (edgexfoundry#3867)

- remove `serviceServer`, since EdgeX v2 does not rely on Core contract Service anymore (see: https://github.com/lf-edge/ekuiper/blob/master/docs/en_US/edgex/edgex_rule_engine_tutorial.md#migrate-to-edgex-v2)
- remove the override of edgex- sink's port, since the default is 6379 now, which will not collide with app-service-configurable's port
- add `connections` and `portable` directory
- specify stream to reuse the connection to EdgeX message bus
- add `connectionSelector` in `eKuiperEdgeXSourceTemplate`
- remove unused kuiper configuration scripts
- remove unused kuiper install scripts `rm *.zip`
- remove unused comment
