feat: Advanced Templating (#823)

Browse Source 
1. Added `helmfile build` command to print final state
Motivation: useful for debugging purposes and some CI scenarios

Ref #780 

2. Template interpolation is now recursive (you can cross-reference release fields) like:
```yaml
templates:
  release:
    name: {{`app-{{ .Release.Namespace }}`}}
    namespace: {{`{{ .Release.Labels.ns }}`}}
    labels:
      ns: dev
```
3. Experimental: Added some boolean release fields interpolation in templates:
```yaml
templates:
  release:
    name: {{`app-{{ .Release.Namespace }}`}}
    namespace: dev
    installedTemplate: {{`{{ eq .Release.Namespace "dev" }}`}}
```

Resolves #818

4. Added more template interpolations: Labels, SetValues
5. Added template interpolation for inline Values
6. Added `helmfile list` command to print target releases in simple tabular form
7. Added release names in some `helm` output messages, e.g.: `Comparing release=%v, chart=%v`
