Also:
- build a custom URL matcher to cope with container image names having a encoded forward slash in them.
- escape node ids in the UI when constructing URLs.
- add a test which fetches all the nodes of all topologies, and update report fixture to have slash in container image names.
This causes detailed node lookups for the grouped-by-process-name view to fail. Also, add a test for process walker trimmming whitespace, and a test the process-by-name view gives the right result.
- Move render.Rpt to test.Report
- Remove report/report_fixture_test.go; it was unused
- Remove report fixture in app/ and make tests use test.Report
- Move expected outputs into render/expected, so they can be reused
