### Description of PR
Zeppelin home directory should include plugins directory. Current Bigtop
zeppelin spec file and install_zeppelin.sh file does not specify plugins
directory
Build will be successful and rpm file will be generated without any error
even if there is no specification about plugins directory.
However when you install rpm and run zeppelin notebook, you will see Logs
Like below

```
So I put specification of plugins dir to spec file and install_zeppelin.sh
### How was this patch tested?
1. modify spec file and install_zeppelin.sh (install plugins dir and
specifying location of plugins dir)
2. run gradle task
```bash
./gradlew zeppelin-clean zeppelin-pkg
```
3. Check "BUILD SUCCESSFULL" message
4. Check RPM file list
```bash
rpm -qlp <ZEPPELIN_RPM> | grep plugins
```
