Various improvements to schema binding

[altro3]

• kotlin 1.7.0
• Improved test for complex OpenAPIDefinition
• Fixed lost default value in schema (on class level)
• Fixed lost default, example, deprecated, accessMode properties, when use Schema on property level
• Fixed rename property when use Schema on property level

Not critical but this code can be written more cleanly with something like:

schemaAnn.enumValue("accessMode", io.swagger.v3.oas.annotations.media.Schema.AccessMode.class)
   .ifPresent(accessMode -> {
          switch(accessMode) {
               case READ_ONLY:
                        schemaToBind.setReadOnly(true);
                         schemaToBind.setWriteOnly(null);
                break;
               case WRITE_ONLY:
                        schemaToBind.setReadOnly(false);
                         schemaToBind.setWriteOnly(null);
                break;
          }
   });

Apart from that is setting write only to null correct?

@graemerocher I don't now, sorry. This block copypasted from swagger lib

@graemerocher Your proposal is not so simple, because would require making the schemaToBind variable finalized. In this case, I think that this block is better left as is.

@graemerocher Hi! Could anyone review my pull requests? Because I want to continue improve this module and now it's already 6 PR open from me and need to merge them so that there are fewer problems with conflicts

@altro3 was away last week, apologies for the delay
