HDDS-2302. Manage common pom versions in one common place

[elek]

What changes were proposed in this pull request?

Some of the versions (eg. ozone.version, hdds.version, ratis.version) are required for both ozone and hdds subprojects. As we have a common pom.xml it can be safer to manage them in one common place at the root pom.xml instead of managing them multiple times.

I would move some of the properties to the root pom.xml to make it easier to manage/change them. (For example change the ratis.version at only one place)

How this patch can be tested?

Do a normal build.

Seems like acceptance test is failing because acceptance.sh looks for <ozone.version> in hadoop-ozone/pom.xml:

https://github.com/apache/hadoop-ozone/blob/e722e4d3a73b4eb6f92b678be83ba32590edc085/hadoop-ozone/dev-support/checks/acceptance.sh#L22

Should be changed:

-OZONE_VERSION=$(grep "<ozone.version>" "$DIR/../../pom.xml" | sed 's/<[^>]*>//g'|  sed 's/^[ \t]*//')
+OZONE_VERSION=$(grep "<ozone.version>" "$DIR/../../../pom.xml" | sed 's/<[^>]*>//g'|  sed 's/^[ \t]*//')

or even:

-OZONE_VERSION=$(grep "<ozone.version>" "$DIR/../../pom.xml" | sed 's/<[^>]*>//g'|  sed 's/^[ \t]*//')
+OZONE_VERSION=$(grep "<ozone.version>" pom.xml | sed 's/<[^>]*>//g'|  sed 's/^[ \t]*//')
