Add profile for generating Swagger documents
This commit adds a profile for generating Swagger documents and creating a tarball containing the swagger.json, swagger.html, and swagger.pdf files. The profile is triggered in any module when tsts are enabled (In other words when the skipTests flag is off), and when the following proerty is set: <swagger.generation.phase>post-integration-test</swagger.generation.phase> This profile assumes that a unit test exists that creates the following file: target/swagger/swagger.json If this file does not exist, the build will fail if the profile is invoked. Therefore, to generate the Swagger documentation tarball, a module must set the swagger.generation.phase propety AND have a unit test that generates the swagger.json file.

+Generating Swagger Documentation
+********************************
+The `Policy Parent Integration POM <https://github.com/onap/policy-parent/blob/master/integration/pom.xml>`_ contains a *generateSwaggerDocs* profile. This
+profile can be activated on any module that has a Swagger endopint. When active, this profile creates a tarball in Nexus with the name
+*<project-artifactId>-swagger-docs.tar.gz*. The tarball contains the fillowing files:
+
+.. code-block:: bash
+
+ swagger/swagger.html
+ swagger/swagger.json
+ swagger/swagger.pdf
+
+The profile is activated when:
+
+1. The following property is defined at the top of the *pom.xml* file for a module
+
+ .. code-block:: bash
+
+ <!-- This property triggers generation of the Swagger documents -->
+ <swagger.generation.phase>post-integration-test</swagger.generation.phase>
+
+ See the `CLAMP runtime POM <https://github.com/onap/policy-clamp/blob/master/runtime/pom.xml>`_ for an example of the usage of this property.
+
+2. Unit tests are being executed in the build, in other wirds when the *skipTests* flag is *false*.
+
+You **must** create a unit test in your module that generates the following file:
+
+.. code-block:: bash
+
+ src/test/resources/swagger/swagger.json
+
+Typically, you do this by starting your REST endpoint in a unit test, issuing a REST call to get the Swagger API documentation. The test case below is an example
+of such a test case.
+
+.. code-block:: java
+
+ @Test
+ public void testSwaggerJson() throws Exception {
+ ResponseEntity<String> httpsEntity = getRestTemplate()
+ .getForEntity("https://localhost:" + this.httpsPort + "/restservices/clds/api-doc", String.class);
+ assertThat(httpsEntity.getStatusCode()).isEqualTo(HttpStatus.OK);
+ assertThat(httpsEntity.getBody()).contains("swagger");
+ FileUtils.writeStringToFile(new File("target/swagger/swagger.json"), httpsEntity.getBody(),
+ Charset.defaultCharset());
+ }
+
+See `this unit test case <https://github.com/onap/policy-clamp/blob/master/runtime/src/test/java/org/onap/policy/clamp/clds/it/HttpsItCase.java>`_
+for the full example.
