Automatically load/import dashboard when creating new container

[saintx]

When starting up a new demo container deployment, we should automatically load/import the dashboard JSON file.

In order to automate this, we need to be able to programmatically perform two tasks:

• Create an index pattern in Kibana
• Import the dashboard JSON file

The former is coming in Kibana 5.0 (see elastic/kibana#5199). It is unclear whether there are any plans to implement the latter at this time. For now, we should continue to manually create the ctia* index pattern and manually import the dashboard after setting up the CTIA server via docker-compose.
