WIP support for cypher directive in relationship properties

[angrykoala]

Description

Support for using @cypher directives in relationship properties

The following will not be supported:

• Aggregate by @cypher fields (both, in edge and node)

Example:

type Movie @node {
    title: String!
    actors: [Actor!]! @relationship(type: "ACTED_IN", direction: IN, properties: "ActedIn")
}

type Actor @node {
    name: String!
    actedIn: [Movie!]! @relationship(type: "ACTED_IN", direction: OUT, properties: "ActedIn")
}

type ActedIn @relationshipProperties {
    screenTimeHours: Float
        @cypher(
            statement: """
            RETURN this.screenTimeMinutes / 60 AS c
            """
            columnName: "c"
        )
    screenTimeMinutes: Int
}
