Streamparse

This release simply makes it possible to override more settings that are in `config.json` at the `Topology` level. You can now add `config = {'virtualenv_flags': '-p /path/to/python3'}` to have some topologies in your project using one version of Python and others using another (Issue 399, PR 402)

This release just adds `options` to `pre_submit_hook` and `post_submit_hook` arguments. This is mostly so you can use the storm workers list inside hooks. (PR 396)

This release simply adds a new feature where the `storm.workers.list` topology configuration option is now set when you submit a topology, so if some part of your topology needs to know the list of Storm workers, you do not need to resort to connecting to Nimbus with each executor to find it out. (PR 395)

Another small release, but fixes issues with `sparse tail` and `sparse remove_logs`.

Features
- Can now specify the number of simultaneous SSH connections to allow when updating virtualenvs or accessing/removing logs from your workers with the `--pool_size` argument. (PR 393)
- The user that is used to remove logs from the Storm workers with `sparse remove_logs` can now be specified with `--user` (PR 393)

Fixes
- `sparse tail` and `sparse remove_logs` do a much better job of only finding the logs that relate to your specified topology in Storm 1.x (PR 393)
- `sparse run` will no longer crash if you have `par` set to a `dict` in your topology. (bafb72b)

Fix issue where `sparse run` would not work without Nimbus properly configured in `config.json` (Issue 391, PR 392)

Small release, but a big convenience feature was added.

Features
- No longer need to specify `workers` in your `config.json`! They will be looked up dynamically by communicating with your Nimbus server. If for some reason you would like to restrict where streamparse creates virtualenvs to a subset of your workers, you can still specify the worker list in `config.json` and that will take precedence. (PR 389)
- Added better error messages for when `util.get_ui_jsons` fails (commit b2a8219)
- Can now pass `config_file` file-like objects to `util.get_config` for if you need to do something like retrieve the config at runtime from a wheel. Not very common, but it is now supported. (PR 390)
- Removed the now unused `decorators` module.

Fixes
- Fixed a documentation issue where the FAQ still referenced the old `ext` module that was removed a long time ago (Issue 388)
