`--retain-values-files` prevents temporary values files that were passed to Helm commands run by Helmfile for debugging purpose.
With that, you can manually rerun helm commands that were logged when `--log-level=debug` is enabled.

* Add option to suppress diff on apply
Add --supress-diff option on apply. Usable for fresh installs when a
lot of output is produces by diff.
Resolves#458
* fix tests for suppress-diff
The addition of `--set k1=v1,k2=v2` and `--values file1 --values file2` was originally planned in #361.
But it turned out we already had `--values` for existing helmfile commands like `sync`. Duplicated flags doesn't work, obviously.
So this actually add `--state-values-set k1=v1,k2=v2` and `--set-values-file file1 --set-values-file file2`.
They are called "state" values according to the discussion we had at #640Resolves#361
* feat: helmfile as a go library
This removes almost all the dependencies from the helmfile core logic to urfave/cli. `main.go` is now a thin wrapper around the core logic implemented in `pkg/app`.
