Kapitan

- Fix for 81
- Clearer message for version check (82)
- Support for jinja2 'do' extension (89)

- Updated reclass
- (<https://github.com/deepmind/kapitan/pull/78>) Support for creating a target secret on compile time, if the secret does not already exist:

yaml
?{gpg:path/to/new_secret|randomstr:32}


If `path/to/new_secret` does not exist under `secrets_path` it evaluates `randomstr:32`, which returns a 32 byte-log random string generated by [secrets.token_urlsafe](https://docs.python.org/3/library/secrets.html#secrets.token_urlsafe) and creates the secret with its content.

- (<https://github.com/deepmind/kapitan/pull/79>) Support for YAML C bindings to improve compilation performance.

If you're using the pip version of Kapitan, you can benefit from YAML C bindings support by running:

Linux: `sudo apt-get install python3-yaml`
Mac: `brew install libyaml`

- Updates to `deepmind/kapitan:ci` Docker image
- `kapitan secrets --write` and `kapitan secrets --update-targets` are now consistent in terms of the recipients list 67
- Significant performance improvement to `kapitan compile` 71
- `kapitan compile` now writes the version to `.kapitan` and future executions will check if the last used kapitan version is <= than the current kapitan version, to keep compilations consistent. You can skip version check by doing `kapitan compile --ignore-version-check`. For more info see 57 and 72
