Ensembler Crash in Docker

[Travmatth]

Expected behavior

Executing deepstate-ensembler should start fuzzers

$ mkdir ensembler_seeds
$ printf "\xab\xcd" >> ensembler_seeds/initial
$ deepstate-ensembler -i ensembler_seeds/ --test examples/IntegerOverflow.cpp

Actual behavior

deepstate-ensembler crashes, complaining of a missing variable:

user@bb2e0f74dd7a:~/deepstate$ deepstate-ensembler -i ensembler_seeds/--test examples/IntegerOverflow.cpp
INFO:deepstate:Setting log level from DEEPSTATE_LOG: 2
Traceback (most recent call last):
  File "/usr/local/bin/deepstate-ensembler", line 11, in <module>
    load_entry_point('deepstate==0.1', 'console_scripts', 'deepstate-ensembler')()
  File "/usr/local/lib/python3.6/dist-packages/deepstate-0.1-py3.6.egg/deepstate/executors/auxiliary/ensembler.py", line 368, in main
    ensembler = Ensembler()
TypeError: __init__() missing 1 required positional argument: 'envvar'

Information about the Issue

Seems to be related to #263, attempted to imitate be65470 by creating an ENSEMBLER_HOME=/usr/local/bin variable and adding it to $PATH, but no change in the crashing status was observed.

Steps to reproduce the behavior

1. Download, build, launch deepstate docker container
2. Run:

$ mkdir ensembler_seeds
$ printf "\xab\xcd" >> ensembler_seeds/initial
$ deepstate-ensembler -i ensembler_seeds/ --test examples/IntegerOverflow.cpp

Well, after my PRs the ensembler is broken and need fixes. See #331 . First step for the fix would be to implement fuzzers synchronization and tests for that. Then the ensembler that spawns and maintain the fuzzers.

Closing since this is captured in #377 which is more up to date
