Reporter API: support splitting output across multiple files #1372

Problem or motivation

Coverage reporters, especially the HTML coverage reporter, produce a single output file.
That approach doesn't scale to schemas with thousands of packages and causes may problems with memory consumption.

Proposed solution

Provide an interface that will allow returning separate datasets for individual files.
Rework or create a new HTML coverage reporter, along with needed changes in java API and other sub-projects to allow for generation of multiple files from one reporter output.
