Generating a shell script

Per ticket 314, a prototype was created to demonstrate generating a shell script of all the calls that ml-gradle makes during mlDeploy. The prototype involves adding a Spring RestTemplate interceptor to ml-gradle, and that interceptor then writes out every HTTP call. A text file is attached to that issue, and its contents are below for easy reference too.

To try this out, just add it to the bottom of your ml-gradle file. Then run "mlDeploy", and check out the "build/curl-(timestamp).txt" file that it generates. Then customize as needed.

dependencies {
    // 3.4.0 or higher should work
	compile "com.marklogic:ml-app-deployer:3.6.0"
}

public class CurlInterceptor implements ClientHttpRequestInterceptor {

	private RestConfig restConfig;

	public CurlInterceptor(RestConfig restConfig, Writer writer) {
		this.restConfig = restConfig;
		this.writer = writer;
	}

	@Override
	public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {
		HttpMethod method = request.getMethod();
		if (HttpMethod.POST.equals(method) || HttpMethod.PUT.equals(method)) {
			HttpHeaders headers = request.getHeaders();
			String contentType = "application/xml";
			if (MediaType.APPLICATION_JSON.equals(headers.getContentType())) {
				contentType = "application/json";
			}

			String payload = new String(body).trim();
			payload = payload.replace("\n","");
			payload = payload.replace("\r","");

			writer.write(String.format(
				"curl -X %s --anyauth -u %s:%s -H \"Content-Type:%s\" -d '%s' %s\n\n",
