extensible DefaultConstraintMaker for persistence

[bdargan]

Added a custom constraint that needs a custom constraint maker to ensure deserialized job will contain the default constraints and the custom constraint.

The recently "open" DefaultConstraintMaker couldn't be sub-classed without hitting inaccessible initialiser build error.

class MyConstraintMaker: DefaultConstraintMaker {
  override public func make(from decoder: Decoder) throws -> [CodableConstraint] {
    var constraints: [CodableConstraint] = try super.make(from: decoder)
    if let constraint = try MyCustomConstraint(from: decoder) { constraints.append(constraint) }
    return constraints
  }
}

queueManager = SwiftQueueManagerBuilder(creator: MyJobCreator())
      .set(serializer: DecodableSerializer(maker: MyConstraintMaker()))

Hey @lucas34, I'm not familiar with the check that failed on Swift / DANGER, do you have any recommendations?
