Pass Relation-Name as Constructor parameter to RelationDef

[srfc]

Issue

• pass relation name as constructor parameter to RelationDef

• Current relation definition example:

object Cast extends RelationDef {
    val starId: ColumnDef[Int] = ColumnDef("star_id")
    val name: ColumnDef[String] = ColumnDef("name")
    val role: ColumnDef[String] = ColumnDef("role")

    override val name: String = "cast"
    override val columns: Set[UntypedColumnDef] = Set(starId, name, role)
}

• Change to:

object Cast extends RelationDef("cast") {
    val starId: ColumnDef[Int] = ColumnDef("star_id")
    val name: ColumnDef[String] = ColumnDef("name")
    val role: ColumnDef[String] = ColumnDef("role")

    override val columns: Set[UntypedColumnDef] = Set(starId, name, role)
}
