Currently swift client does not allow content type to be specified when upload an object. It does not allow a user to change content type neither. This patch will allow a user to specify content type by using upload command or modify the content type by using post command. For example: 1. To upload an object with specific content type: swift upload -H content-type:applicaiton/xml con1 file1 2. To modify an object to a specific content type: swift post -H content-type:application/josn con1 file1 This patch also allow a client to specify other request headers. Change-Id: I12db83a1d465285e0906889cc67dfaa44e059568 Fixes: bug #1154621
