- base load graph x-axis on data, not a hardcoded window
- format memory dynamically to scale
- add some tests for the immutability of metrics
- use ps.List for Sample storage, so it is immutable. Have to implement custom marshalling
- adding tests for report.Metrics
- check the ordering of the json samples
- Make the nil value for Metrics valid.
- Sort samples from oldest to newest on the wire.
We want to be able to import test from packages like probe/endpoint, in
order to use utility functions like poll. But that causes an import
cycle with the current layout. We got around this using dot-imports so
far, but it's ugly and unnecessary: fixture can be its own package.
