Follows #1546. This PR allows API Platform to add useful SQL
JOIN
clauses and to remove the useless ones according to properties selected by the client using the property filter.That's a massive performance improvement when using this filter.
I'll also use this feature later to improve the generated SQL queries when using GraphQL. It will allow to only fetch what is required for a given GraphQL query while to reducing dramatically the number of issued SQL queries for a whole GraphQL request.
