Chaostoolkit

Changed

- Handle RC versioning when building release
- Pin dependency versions

Changed

* Remove `NoReturn` import as it is not available prior Python 3.6.5 [90][90]

[90]: https://github.com/chaostoolkit/chaostoolkit/issues/90

Added

- add `info` command to display basic information such as version of the
toolkit core library or installed extensions. Display also the current
settings [64][64]

Changed

- strip command name before sending it to check newer version as sometimes
we get a tabulation character in there
- swap `logger.warn` for `logger.warning` as the former is obsolete

Added

- send a `RunFlowEvent.RunDeviated` event in addition to other events when the
steady state deviated after the experimental method [56][56]

[56]: https://github.com/chaostoolkit/chaostoolkit/issues/56

Added

- a new global flag `chaos --settings <path>` to explicitely specify the
location of the Chaos Toolkit settings file
- experiments can now also be loaded from a HTTP(s) resource (with or without
auth) as per [53][53]

[53]: https://github.com/chaostoolkit/chaostoolkit/issues/53

Changed

- by default, the run command will now set the exit code to 1 when the
experiment is not successful (interrupted, aborted or failed). This can be
bypassed by plugins so they have the opportunity to process the journal as
well. In that case, they must set the exit code themselves to play nicely.

Changed

- Do not notify of experiment validation when running it (too noisy)
- Encode date, datetime, decimal and UUID to JSON explicitely
