Support all delete use cases

[fcoury]

Our implementation only deletes all records that match the query.

We need to add proper support for deleteOne and ordered:

[Document({"delete": String("test_16deae6e-2afa-42a6-b129-ceef7d46c19b"), "deletes": Array([Document({"q": Document({"a": Int32(1)}), "limit": Int32(0)})]), "ordered": Boolean(true), "$db": String("db_test")})]
