`npm backend:dev` expects a psql on localhost:5432

[landryb]

Describe the bug
developing in the mapstore2 submodule uses an h2 database so npm start works ootb by default.

Would it be possible/better to use an h2 database in the ms2-georchestra project instead of expecting a psql database on localhost ?

@Gaetanbrl @pierrejego what do you think about it ?
