6115 total count only connection

[angrykoala]

Description

Cypher optimisation on queries with only totalCount. For example:

query {
    moviesConnection(where: { title: { eq: "Forrest Gump" } }) {
        totalCount
    }
}

With this changes, the Cypher avoids querying the actual nodes to improve query performance and networking
