Setup for calling trace_redactor

Add the initial setup and flow for redacting traces before delivering to
app storage.  With this change when a trace is completed a new processes
will be created to run the trace_redactor binary.  The newly redacted
file will then be delivered to app storage and the unredacted file will
be deleted.
