- Simple copy-paste for the most part from sync job. I had started down
the path of adding in a meta PluginCommand directive and trying to make it
more modular, but in the end there are some small differences between
the execution that were a bit difficult to model and it just got ugly.
Figured keeping it simple would be easier to manage
If the chart is in directory, for example, `./my/chart` the `helmfile -f my.yaml sync` will fail.
This PR will check if the chart starts with `/`, `./` or `../` and will transform it in a full path of the chart directory.
