Enhances Helmfile to print more helpful message on error while calling `exec` template function.
Helmfile has been printing error messages like the below:
```
in ./helmfile.yaml: error during helmfile.yaml.part.0 parsing: template: stringTemplate:5:8: executing "stringTemplate" at <exec "./exectest.sha" (list)>: error calling exec: exit status 1
```
Adding captured stdout and stderr, with some indentation to make it readable, it now produces the following message on missing executable:
```
$ make build && ./helmfile build
go build
in ./helmfile.yaml: error during helmfile.yaml.part.0 parsing: template: stringTemplate:5:8: executing "stringTemplate" at <exec "./exectest.sha" (list)>: error calling exec: fork/exec ./exectest.sha: no such file or directory
COMMAND:
./exectest.sha
ERROR:
fork/exec ./exectest.sha: no such file or directory
```
On non-zero exit status without output:
```
$ make build && ./helmfile build
go build
in ./helmfile.yaml: error during helmfile.yaml.part.0 parsing: template: stringTemplate:5:8: executing "stringTemplate" at <exec "./exectest.sh" (list)>: error calling exec: exit status 1
COMMAND:
./exectest.sh
ERROR:
exit status 1
```
On non-zero exit status with output:
```
$ make build && ./helmfile build
go build
in ./helmfile.yaml: error during helmfile.yaml.part.0 parsing: template: stringTemplate:5:8: executing "stringTemplate" at <exec "./exectest.sh" (list)>: error calling exec: exit status 2
COMMAND:
./exectest.sh
ERROR:
exit status 2
COMBINED OUTPUT:
out1
err1
```
Resolves#1158
`--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.
Resolves ##1117
* 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
When chart is not set, an exception without any hints occure due
normalizeChart tries to access the first character of a 0 length string.
Properly inform user of missing chart.
This makes it possible to pass the API Capabilities to helmfile when executing a task that does not render against an actual cluster (diff, template, apply).
Resolves#1014
Adds support for indexed key arguments and escaped dot arguments to `--state-values-set`.
Things like `--state-values-set config\.yml.something=abc` or `--state-values-set config.something[0]=abc` can be passed in the command line.
Resolves#899
It looks like during the beta phase the testing functionality was tweaked / changed back during the beta phase but has since been returned back to how it worked originally.

When helmfile is run with `--environment NAME` and there was a base hemlfile that misses `environments`, helmfile had been trying to load env values for NAME and failing.
A base helmfile is allowed to reference values from within itself, but that's optional. In other words, a base helmfile that misses the env is okay as long as it doesn't self-reference env values.
So, this change allows missing env and env values while loading base helmfile. After loading, a base helmfile can fail due to referencing missing env values, but that's okay.
Fixes#1008
