[Java][JavaResteasyServerCodegen] dateLibrary=java8 is ignored and joda added instead

[user667]

Description

When generating server code via io.swagger.codegen.v3.generators.java.JavaResteasyServerCodegen using dateLibrary=java8 then com.fasterxml.jackson.datatype.joda.JodaModule and some is added to the JacksonConfig class instead of com.fasterxml.jackson.datatype.jsr310.JavaTimeModule. This causes compilation to fail.

Swagger-codegen version

This happens when using version 3.* (3.0.12-SNAPSHOT) and 2.4.* (2.4.9-SNAPSHOT).

Swagger declaration file content or url

Any.

Command line used for generation

Using Maven to generate the code via https://gist.github.com/user667/57dd1c96de0fbaeacf850a99f9cd0749

Steps to reproduce

Simply generate the code via Maven from any valid YAML Swagger declaration file.

This problem stems from the fact that the mustache template files (./modules/swagger-codegen/src/main/resources/JavaJaxRS/resteasy/JacksonConfig.mustache for version 2.4.* and swagger-codegen-generators/src/main/resources/handlebars/JavaJaxRS/resteasy/JacksonConfig.mustache in project generators for version 3.0.*) do not contain the switch for java8/joda.
