Add shortcut addAs methods to DocumentWriteSet

[sammefford]

To align with the rest of the Java Client API, DocumentWriteSet should have addAs methods that accept a content object then uses the handle registry to lookup the appropriate handle for the object.

[sammefford]

This is implemented both on develop and 3.0-develop

Added the following method to TestDatabaseClientConnection.java

// Test to validate that addAs with a java.io.object in DocumentWriteSet writes the document.
    @Test
    public void testAddAs() throws Exception {

        System.out.println("Running testAddAs");

        String[] docId = {"aggr1.xml", "aggr2.xml", "aggr3.xml"};

        try {
            TextDocumentManager docMgr = client.newTextDocumentManager();
            docMgr.setMetadataCategories(Metadata.ALL);
            DocumentWriteSet writeset = docMgr.newWriteSet();

            DocumentMetadataHandle mhRead = new DocumentMetadataHandle();       
            InputStream inputStream1 = new FileInputStream("src/test/java/com/marklogic/client/functionaltest/data/" + docId[0]);
            InputStream inputStream2 = new FileInputStream("src/test/java/com/marklogic/client/functionaltest/data/" + docId[1]);

            writeset.addAs(docId[0], inputStream1);
            writeset.addAs(docId[1], inputStream2);
            writeset.addAs(docId[2], inputStream3);
