Define a proxy for plugin installation

Browse source 
Address the issue [ansible-elasticsearch
#4](https://github.com/elastic/ansible-elasticsearch/issues/4) which
add proxy for plugin installation and more generally es_proxy_host and
es_proxy_port for global usage.

Right now, it’s only used for plugins installation. In the futur, it
can be used (or defined) in the java_opts within the default file for
instance (elasticsearch.j2)

### Proxy
To define proxy globaly, set the following variables:
* ```es_proxy_host``` - global proxy host
* ```es_proxy_port``` - global proxy port
To define proxy only for a particular plugin during its installation:
```
es_plugins:
- plugin: elasticsearch-cloud-aws
version: 2.5.0
proxy_host: proxy.example.com
proxy_port: 8080
```
> For plugins installation, proxy_host and proxy_port are used first if they are defined and fallback to the global proxy settings if not.
## Notes
* The role assumes the user/group exists on the server. The elasticsearch packages create the default elasticsearch user. If this needs to be changed, ensure the user exists.
