[Draft] Add Integration for Missile Map

[navnit-crest]

Proposed commit message

Create a new integration package named missile_map and add the Missile Map dashboard.

The Missile Map dashboard includes a custom map visualization that uses the Elastic Map Service to add a base map. For the marks (path, text, arc, etc.) and animations, it uses the Vega visualization framework within Kibana.
