HBASE-29531 Addendum fix missing charset in RS Status page

[PDavid]

Made sure that the Content-Type HTTP header includes the UTF-8 charset when the RegionServer status web UI page is returned so that it is consistent with Master Status web UI page.

[PDavid]

This problem was uncovered in #7568 (comment).
This seems to only be an issue on branch-2 and branch-2.6 (not a problem on master or branch-3).
