This change enhances helmfile to accept terraform-module-like URLs in nested state files a.k.a sub-helmfiles.
```yaml
helmfiles:
- # Terraform-module-like URL for importing a remote directory and use a file in it as a nested-state file
# The nested-state file is locally checked-out along with the remote directory containing it.
# Therefore all the local paths in the file are resolved relative to the file
path: git::https://github.com/cloudposse/helmfiles.git@releases/kiam.yaml?ref=0.40.0
```
The URL isn't equivalent to terraform module sources. The difference is that we use `@` to distinguish between (1) the path to the repository and directory containing the state file and (2) the path to the state file being loaded. This distinction provides us enough fleibiity to instruct helmfile to check-out necessary and sufficient directory to make the state file works.
Under the hood, it uses [hashicorp/go-getter](https://github.com/hashicorp/go-getter), that is used for [terraform module sources](https://www.terraform.io/docs/modules/sources.html) as well.
Only the git provider without authentication like git-credentials helper is tested. But theoretically any go-getter providers should work. Please feel free to test the provider of your choice and contribute documentation or instruction to use it :)
Resolves#347
```yaml
environments:
default:
missingFileHandler: Warn
values:
- path/to/values.yaml
secrets:
- path/to/secrets.yaml
```
`missingFileHandler` set to `Warn`, `Info`, or `Debug` results in helmfile NOT stop when `path/to/values.yaml` or `path/to/secrets.yaml` is missing.
Resolves#548
While implementing the above feature, I also found a bug that has been causing #559. This also fixes that.
To verify it is actually fixed, create an example helmfile.yaml that looks like the below, and run `helmfile diff`:
```
$ cat helmfile.yaml
environments:
default:
secrets:
- env-secrets.yaml
releases:
- name: myapp
chart: nginx
namespace: default
secrets: [secrets.yaml] # Notice this file does not exist
values:
- ingress:
enabled: true
$ helmfile diff
could not deduce `environment:` block, configuring only .Environment.Name. error: failed to read helmfile.yaml.part.0: environment values file matching "env-secrets.yaml" does not exist
in ./helmfile.yaml: failed to read helmfile.yaml: environment values file matching "env-secrets.yaml" does not exist
```
Fixes#559
This enhances helmfile's internal environment values files loader to expand glob patterns (#606)
Fixes the existing bug that helmfile was unable to load environment values file from absolute path (#549)

* Improve code organization
To make sure it is still readable after upcoming changes to helmfile
* feat: `helmfile deps` to update dependencies of all the local charts
Resolves#450
* feat: helmfile updates repos and build deps by default
But not update deps. Use `helmfile deps` to update deps, and provide `--skip-deps` to skip updating repos and builds deps in sync/diff/apply/template
Resolves#415
* Improve integration test coverage
