Add mongodb support out of the box

[vito-vanhecke]

User needs these commands:
grant db_developer_role to schema ;

grant soda_app to schema;

-- SELECT_CATALOG_ROLE isn't necessary.
grant select_catalog_role to schema;

local-ords compose should include
27017:27017
as extra port.

conn string will look like this:
mongodb://{schema}:{schema_password}@{localhost/public_ip}:27017/{schema}?authMechanism=PLAIN&authSource=$external&ssl=true&retryWrites=false&loadBalanced=true&tlsAllowInvalidCertificates=true
