HADOOP-17908. Add missing RELEASENOTES and CHANGELOG to upstream.

[iwasakims]

https://issues.apache.org/jira/browse/HADOOP-17908

RELEASENOTES and CHANGELOG of 2.10.1, 3.1.4 and 3.3.0 are missing in trunk.

While CHANGES* were renamed to CHANGELOG* by HADOOP-14671, there are some CHANGES files left. I would like to rename those to CHNAGELOG here for consistency.

$ find . -name 'CHANGES*'
./hadoop-common-project/hadoop-common/src/site/markdown/release/2.10.0/CHANGES.2.10.0.md
./hadoop-common-project/hadoop-common/src/site/markdown/release/3.1.2/CHANGES.3.1.2.md
./hadoop-common-project/hadoop-common/src/site/markdown/release/3.1.3/CHANGES.3.1.3.md

hadoop-common-project/hadoop-common/src/site/markdown/release/2.10.0 contains both CHANGES.2.10.0.md and CHANGELOG.2.10.0.md. Since the contents of current CHANGELOG.2.10.0.md is invalid, I replaced it with the contents of current CHANGES.2.10.0.md (and removed the CHANGES.2.10.0.md).

HTML files under "Changelog and Release Notes" pages (hadoop-project/hadoop-project-dist/hadoop-common/release/*) are generated by mvn site regardless of the file names.

Scripts (of Yetus) seem to expect CHANGELOG.

Generated index.html of "Changelog and Release Notes" (hadoop-project/hadoop-project-dist/hadoop-common/release/index.html) can be verified by building docs with -Preleasedocs like

$ mvn site site:stage -Preleasedocs -DstagingDirectory=/var/www/html/hadoop-site/trunk

The patch has 1 line(s) that end in blanks.

The relevant file (RELEASENOTES.3.3.0.md) are part of already published release artifacts. I think it should be added as is.
