Repository: theacodes/nox (python)

Issue:
Some conda commands not logged.
When using `venv_backend="conda"`, the `conda create` command is not logged, even if `-v` is provided, since `log=False` is hard-coded in [`nox/virtualenv.py`](https://github.com/theacodes/nox/blob/master/nox/virtualenv.py#L243):

```python
        nox.command.run(cmd, silent=True, log=False)
```

From the docs, I expected that running `nox -v` would log all commands.

Pull request description:
Conda logs now respect nox.options.verbose.
Fixes #345 

First pass at this, I basically just copied the implementation from #371.
