Data exploration features for the Query Builder

[kislyuk]

Need

Expressed as a high-level user stories:

• As a researcher with a keyboard, DCP developer, or data wrangler, I want the ability to explore the HCA's data model and documentation in a visual, intuitive way, so that I can understand what metadata is available to me in doing my work.

• As a researcher with a keyboard, DCP developer, or data wrangler, I want IDE autocompletion on the metadata schema, so that I can more quickly iterate on understanding and searching through HCA metadata.

Approach

Build out an interactive development features into the Query Service's query builder UI. See sub-issues for feature details.

High level goals that this toolkit helps pursue:

• Users looking for information prompted by our UX study
• Data wranglers performing spot checks/exploratory analysis
• Following breadcrumbs from data tracker (find all metadata associated with a stuck dataset)
