[tor-commits] [stem/master] Support additional test torrc options

Support additional test torrc options
Teor would like to run stem's integ tests against a Chutnet network...
https://trac.torproject.org/projects/tor/ticket/30702
Highly unusual use case, but making it possible. Stem now accepts a
STEM_TEST_CONFIG environment variable that overwrites any internal
testing configuration values (see test/settings.cfg), along with
a 'integ.extra_torrc' option.
So to use this...
1. Write a file that overwrites our integ.extra_torrc
configuration. Available macros include...
[DATA_DIR]
[OR_PORT]
[SOCKS_PORT]
2. Set STEM_TEST_CONFIG to the path of that file.
3. Run our integ tests, and check the beginning of the output where it says
'writing torrc' to confirm that the torrc looks as you expect.
For example...
% cat /home/atagar/Desktop/stem/my_test_config
integ.extra_torrc
|Nickname Demo[OR_PORT]
|FetchUselessDescriptors 1
% export STEM_TEST_CONFIG=/home/atagar/Desktop/stem/my_test_config
% ./run_tests.py --integ
...
Setting up a test instance...
making test directory (/home/atagar/Desktop/stem/test/data)... done
configuring logger (/home/atagar/Desktop/stem/test/data/log)... done
writing torrc (/home/atagar/Desktop/stem/test/data/torrc)... done
# Configuration for stem's integration tests
