[ZEPPELIN-1972] Preserve context classloader
### What is this PR for?
`IMain.interpret` changes current thread's context classloader. It may
cause different issues and definitely is the reason of
[ZEPPELIN-1738](https://issues.apache.org/jira/browse/ZEPPELIN-1738) test
failures.
It's a known scala bug. See https://issues.scala-lang.org/browse/SI-9587
As a workaround we need to save and restore context classloader manually
### What type of PR is it?
Bug Fix
### What is the Jira issue?
[ZEPPELIN-1972](https://issues.apache.org/jira/browse/ZEPPELIN-1972)
### How should this be tested?
Run ignite interpreter test and ignite sql interpreter test in the same
thread
```
mvn test -pl ignite -am -Pscala-2.11
-Dtest=org.apache.zeppelin.ignite.IgniteInterpreterTest#testInterpret,org.apache.zeppelin.ignite.IgniteSqlInterpreterTest#testSql
-DfailIfNoTests=false
```
### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
