#6720: added tests for enermaps API

Ignore test that uses remote sources

Removed out-of-scope test

REST plugin accepts optional Request Headers parameters as json map, e.g. {Accept:application/json}. This is useful to support PostgREST endpoints: they need a param in the header to return proper json. request headers must also be exploited for the pagination (not implemented in this commit). More details on PostgREST at https://postgrest.org/en/stable/api.html....
