closes #84

…moved

Due to #10656

Closes #84.

Sadly netcdf library is not Apache2 License compatible so we should not package it anymore.

For users who wants to use it, they can add manually [netcdf librairies](http://www.unidata.ucar.edu/software/thredds/current/netcdf-java/) in `plugins/mapper-attachments` dir and they will get the support back.

Closes elastic#84.

Follow up for elastic#84.

Sounds like that httpcore is pulled by netcdf libs. Note that we wrote in elastic#84 that we were removing support for netcdf file types.

```xml
<!-- Not Apache2 License compatible -->
<exclusion>
    <groupId>edu.ucar</groupId>
    <artifactId>netcdf</artifactId>
</exclusion>
```

Apparently the removal was not entirely done.

Adding exclusion the following exclusions will fix that:

```xml
<!-- Not Apache2 License compatible -->
<exclusion>
    <groupId>edu.ucar</groupId>
    <artifactId>cdm</artifactId>
</exclusion>
<!-- Not Apache2 License compatible -->
<exclusion>
    <groupId>edu.ucar</groupId>
    <artifactId>httpservices</artifactId>
</exclusion>
<!-- Not Apache2 License compatible -->
<exclusion>
    <groupId>edu.ucar</groupId>
    <artifactId>grib</artifactId>
</exclusion>
<!-- Not Apache2 License compatible -->
<exclusion>
    <groupId>edu.ucar</groupId>
    <artifactId>netcdf4</artifactId>
</exclusion>
```

With that, we don't pull anymore http* client/core/component libs:
