feature: add noreturn opt for some DML operations

[GRISHNOV]

This patch introduces noreturn opt for DML operarions:

• insert, insert_object, insert_many, insert_object_many
• replace, replace_object, replace_many, insert_object_many
• upsert, upsert_object, upsert_many, upsert_object_many
• update
• delete

The opt allows to suppress returning successfully processed tuple(s).

• Tests
• Changelog
• Documentation

it was decided to return to the idea:

• nil, nil for a completely successful batch
• nil, err if at least one tuple failed

Let's change performance test cases to use noreturn
