What changes were proposed in this pull request?

Now, if I accident to connect unexpected SCM since i specify the wrong ozone-site.xml file, the OM cannot startup and through exception SCM_VERSION_MISMATCH_ERROR, but i really don't know what happened. After this PR, you can get the following concrete and complete information about the mismatch clusterId and scmId.

Something like this following:

2020-07-30 23:50:46,759 ERROR om.OzoneManager (OzoneManager.java:<init>(413)) - clusterId from localhost/127.0.0.1:9863 is CID-986bb182-6cf5-43c6-8ad0-979eb7353589, but is CID-986bb182-6cf5-43c6-8ad0-979eb73535891 in /tmp/metadata/om/current/VERSION
