This commit moves Write function to separate yaml package, and makes it available to anyone for dumping documents in single file, with correct yaml separators '---', '...'. This will allow, for example dumping of filtered from bundle documents to disk or any writer, like Stdout, for debugging purposes. Specifically it will be used as part of `airshipctl cluster initinfra` command as a buffer for delivering resources to kubernetes cluster. Change-Id: I780e3f2d2ff446b8787153f500d04d10487ed71b
