We want to explore how we can natively support complex variables. They should be imported by default, and stored in Elasticsearch as complex variables.

In addition:

• We want to be able to return the complete complex variable value
• We want to be able to group reports by complex variable properties (arrays can be excluded from this selection, objects can be explored as complex variables themselves)
• We want to be able to distribute reports by complex variable properties (arrays can be excluded from this selection, objects can be explored as complex variables themselves)
