Generate windows installer

Add `nsis-maven-plugin` in a new platform profile `win-installer` and NSIS resources to generate Windows installer.

Steps to generate Windows installer:

* Build entire project with:
```
mvn bundle:clean clean install bundle:install
```

or, avoiding tests:

```
mvn bundle:clean clean install bundle:install -Dmaven.test.skip=true
```

* Generate windows installer with:
```
mvn -P win-installer clean install -pl :platform
```

It is generated in folder `platform\target` like the other release artifacts.
