Most consumers of util.ExecCommand() need to convert the returned []byte format of stdout and/or stderr to string. By having util.ExecCommand() return strings instead, the code gets a little simpler. A few commands return JSON that needs to be parsed. These commands will be replaced by go-ceph implementations later on. For now, convert the strings back to []byte when needed.
