ZEPPELIN-469 Interpreter process loads unnecessary classes
Addresses issue https://issues.apache.org/jira/browse/ZEPPELIN-469
This PR fixes problem by remove `export ZEPPELIN_CLASSPATH`, so classpath
from bin/zeppelin-daemon.sh is not propagated bin/interpreter.sh.
It can be verified by printing System classloader inside of notebook, like
```scala
val cl = ClassLoader.getSystemClassLoader()
val ucl = cl.asInstanceOf[java.net.URLClassLoader]
ucl.getURLs.foreach(u=>println(u))
```
Result is
Before
```
cl: ClassLoader = sun.misc.Launcher$AppClassLoader@36c51089
ucl: java.net.URLClassLoader = sun.misc.Launcher$AppClassLoader@36c51089
