> DFSUtil#getInfoServer() returns only the authority (i.e., host+port) when searching for
the http / https server. This is insufficient because HDFS-5536 and related jiras allows NN
/ DN / JN to open HTTPS only using the HTTPS_ONLY policy.
> This JIRA addresses two issues. First, DFSUtil#getInfoServer() should return an URI instead
of a string, so that the scheme is an inherent parts of the return value, which eliminates
the task of figuring out the scheme by design. Second, it introduces a new function to choose
whether http or https should be used to connect to the remote server based of dfs.http.policy.
