Add InheritMaps to avoid @Maps duplication

[slemesle]

Some times we need to reproduce the exact same configuration @Maps multiple times in the mapper.

To avoid code duplication we should introduce the @InheritMaps which will apply the configuration from an inherited @Maps with same type to type mapping. Only the couple means something since configuration are bidirectional.

Sample codes :

@Mapper
public interface ExtendMapper {

    @Maps(withCustomFields = {
            @Field({"Proposal.passenger.age", "ProposalDto.passengerAge"}),
            @Field({"passenger.card", "passengerCard"}),
            @Field({"Proposal.passenger.date", "ProposalDto.passengerDate"})
    }) ProposalDto asProposalDto(Proposal proposal);

    @InheritMaps
    Proposal asProposal(ProposalDto proposal);

    @InheritMaps
    Proposal asProposal(ProposalDto proposal, Proposal out);
}

@Mapper
public interface ExtendNamedMapper {

    @Maps(withCustomFields = {
            @Field({"Proposal.passenger.age", "ProposalDto.passengerAge"}),
            @Field({"passenger.card", "passengerCard"}),
            @Field({"Proposal.passenger.date", "ProposalDto.passengerDate"})
    }) ProposalDto asProposalDto(Proposal proposal);

    @Maps(withIgnoreFields = {"passengerAge", "passengerDate", "passenger", "passengerCard"})
    ProposalDto asReducedProposalDto(Proposal proposal);

    @InheritMaps(method = "asReducedProposalDto")
    Proposal asProposal(ProposalDto proposal);

    @InheritMaps(method = "asReducedProposalDto")
    Proposal asProposal(ProposalDto proposal, Proposal out);
}
