Script to generate reports from logs, and bug fixes:

* log_report.py is a script to generate debugging reports and combine the logs
of the locally run mainchain and sidechain servers.

* Log address book before pytest start

* Cleanup test utils

* Modify log_analyzer so joins all logs into a single file

* Organize "all" log as a dictionary

* Allow ConfigFile and Section classes to be pickled:
This caused a bug on mac platforms. Linux did not appear to use pickle.

* Add account history command to py scripts

* Add additional logging

* Add support to run sidechains under rr:

This is an undocumented feature to help debugging.
If the environment variable `RIPPLED_SIDECHAIN_RR` is set, it is assumed to
point to the rr executable. Sidechain 0 will then be run under rr.
