add geocris initial data

[meomancer]

Adding initial data for geocris Note :

• i can't find sub distric and village data, so need to update some views
• geoserver can't show the buildings (i think because of village is not found)
• for example flood data, can be found here : https://github.com/kartoza/geocris-inasafe-fba/blob/959ee7139b6f6ecd5f0b8853a7eeba410ebaa402/fixtures/tests/grenada.flood.geojson
