[ZEPPELIN-2139] Interpreters based on scala_2.11 aren't installed correctly
### What is this PR for?
pom variables such as `${scala.version}` are not replaced to value when you
do mvn install.
This causes leaf poms to look for this value in parent pom, which is always
`2.10.5` and bring scala library dependency conflict. For example,
zeppelin-flink_2.11 will have scala 2.10.5 as dependency.
This PR fixes this problem by using maven flatten plugin.
### What type of PR is it?
Bug Fix
### What is the Jira issue?
[ZEPPELIN-2139](https://issues.apache.org/jira/browse/ZEPPELIN-2139)
### How should this be tested?
```
$ ./dev/change_scala_version.sh 2.11
$ mvn clean install -pl
'zeppelin-server,zeppelin-zengine,zeppelin-interpreter,flink' -am -DskipRat
-DskipTests -Pscala-2.11
```
Open
`~/.m2/repository/org/apache/zeppelin/zeppelin-flink_2.11/0.8.0-SNAPSHOT/zeppelin-flink_2.11-0.8.0-SNAPSHOT.pom`
file and see if scala related libraries dependency version is set to 2.11.7
### Screenshots (if appropriate)
### Questions:
* Does the licenses files need update? no
* Is there breaking changes for older versions? no
* Does this needs documentation? no
