Documentation adjustment to v2

[MarcOverIP]

The documentation on the wiki should be updated to include:

• [x] installation steps for new v2 dockerized setup
• [x] Explanation of install-elkserver.sh parameters
• [x] How to use custom logstash filters
• [x] include the option for deployment for ansible. This is just a reference to external ansible scripts
• [ ] Updated list on the field names and types (now still includes the old names)
• [x] Detailed explanation of alarms and config.json parameters
• [ ] how to build an alarm / notification connector

Anything else?

how to build an alarm / notification connector?

[MarcOverIP]

@fastlorenzo you are better entitled to document on custom alarms and notification connectors. I've done a significant push on the other items, still some to do on the field names. But we're getting there.
