Deprecate @IgnoreFields and @Fields in favor of a new annotation

[slemesle]

Selma has way too much annotations, we want to simplify it.

A new @maps annotation will be used to describe mappings configuration on the method scope.
So we will have only @Mapper annotation useable at type level and @maps useable for the interface methods.

This will allow us to scope the custom mappers.

New @maps annotation for:

• IgnoreFields
• Custom field to field
• Custom enum mapper
• Ignore missing properties
