customize property name

Discussed in https://github.com/swagger-api/swagger-codegen/discussions/11103

In the generated Java model code, we're assuming we want to generate a model that using the same name as defined in the schema. Thus, as long as the schema name does not violate certain rules, the generated model will always be

@JsonProperty("name")
private final String name;

but sometimes we want to customize the property name or the variable name by self-defined it, such as

@JsonProperty("n")
private final String name;

Is it possible to do so with swagger?

The issue names no implementation file, template, or test. Start by tracing Java model generation and how schema property names become @JsonProperty values; done means documenting or implementing a supported way to choose a different serialized property name from the generated Java field name, with coverage for the example case.
