Tool for adding testcase from flowtrace

[jonnor]

Flowtrace can be captured of issues found in production. Want to be able to go quickly to a reproducable test-case - to understand, fix and ensure issue does not happen again.

A tool could allow specifying a flowtrace, and an an fbp-spec file (with already existing topic/fixture/testcases). It would read the test topic, then go through the trace to find the inputs/output to that component. Then create a testcase with this input and skeleton/empty expectations, and modify the YAML file to include the new testcase.

Tool would be used (primarily) manually by developers. But one can imagine automated uses, where a production failure would automatically create testcase, put it through CI against newest/development version of the software.
