HBASE-29531 Migrate RegionServer Status Jamon page back to JSP

[PDavid]

This is the 2/3 step of the Jamon to JSP migration: the Region Server Status page.

Did the migration the same way as for the Master Status page: #6875

Migrated the Jamon code to JSP as close as possible. Extracted the duplicated formatZKString method to new java class: ZKStringFormatter and added unit tests.

Changed the Region Server Status page back to /regionserver.jsp. Made sure that /rs-status redirects to /regionserver.jsp.

Extracted the BlockCache inline CSS styles to hbase.css file. Also extracted the large BlockCache Hit Ratio periods paging JavaScript code to separate .js file.

Introduced a src/main/resources/hbase-webapps/common directory where we can place common JSP files which are used by both Master and RegionServer JSP pages. This required to adjust the JSP compiler Maven Antrun plugin a bit.

Extracted the inline tablesorter initialization JavaScript code to separate file.

This is a backport of #7371 to branch-3. I cherry-picked the 7892207 commit which applied cleanly.

Also cherry-picked #7416 to fix TestMasterStatusUtil.testGetFragmentationInfoTurnedOn.

Testing

Tested this locally the same way as described here: #7371 (comment)

Also configured HBase in pseudo-distributed mode and checked the RS Status page.

org.apache.hadoop.hbase.replication.TestNamespaceReplication failed in the PR build. I think it is unrelated to the changes and it run successfully locally for me.
