Elasticsearch export

[Nishan8583]

Hello

I have an export function for Elasticsearch. The export file is in exporters/es/es.go. Changes on others files were made accordingly. ELK is used a lot by security engineers and I had do some hacky stuff to export logs from OpenVAS to Elasticsearch in the past. So I hope adding a export mechanism for Elasticsearch will help this project.

Note: make was not working from dev branch, so had to manually build it for testing.

Thanks for the PR @Nishan8583. Merging this into dev, after which I'll be making some changes to remove the CLI args for elasticsearch, and instead add support for using it from the reporting config.

@Nishan8583 follow up changes - #973, now instead of CLI, we can feed the ES config details in the reporting configuration file and can be used with -report-config config.yaml, thanks again for adding this support.
