[HBASE-19366] Backport to branch-1 HBASE-19035 Miss metrics when coprocessor use region scanner to read data

• Type: Sub-task
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 1.4.0
• Component/s: metrics

Release Note

1. Move read requests count to region level. Because RegionScanner is exposed to CP.
2. Update write requests count in processRowsWithLocks.
3. Remove requestRowActionCount in RSRpcServices. This metric can be computed by region's readRequestsCount and writeRequestsCount.

Description

Making subissue to backport the parent issue to branch-1. I'll attach first attempt at a backport. It is failing in TestRegionServerMetrics in an assert.

Making a new issue because time has elapsed since parent went into master and branch-1 and I want to resolve the parent. Thanks. FYI zghaobac If you've input, just say sir and I can take another look.
