[Java] Play! Framework 2.4 WS client support + retrofit2 (#4270)

* implemented core integration with play 2.4 ws

* added shell script to test on CI

* added shell script to composite file for all java generators

* added some comments
changed promise param to Response<T> to allow access to http status code and raw response if needed

* removed unnecessary whitespace changes

* added java7 compatibility, play ws deps to pom.xml

* added generated play24 client

* fixed imports

+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell Swagger Codgen to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md

+
+## Requirements
+
+Building the API client library requires [Maven](https://maven.apache.org/) to be installed.
+
+## Installation & Usage
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn deploy
+```
+
+Refer to the [official documentation](https://maven.apache.org/plugins/maven-deploy-plugin/usage.html) for more information.
+
+After the client library is installed/deployed, you can use it in your Maven project by adding the following to your *pom.xml*:
+
+```xml
+<dependency>
+    <groupId>io.swagger</groupId>
+    <artifactId>swagger-java-client</artifactId>
