This is a successor to #440 rebuilt on top of #594 so that we can merge this while we are still at Hemlfile v0.x without worrying any backward-incompatibility. Much appreciation to @yxxhero for the original work!

* feat: Helmfile V1 mode
We add a new "V1 mode" to Helmfile so that you can seemlessly upgrade Helmfile from the current v0.x to the upcoming v1.0.
The idea is that we build both v0 and v1 binaries from the same tagged commit within the main branch, with different defaults for the "V1 mode"- the V1 mode is disabled by default for v0.x binaries, while it is enabled by default for v1.x binaries.
The V1 mode can be overrode at runtime via envvar. That is, even after upgrading the binary to v1, you will not see any backward-incompatible changes while you explicitly set an envvar, `HELMFILE_V1MODE=true`, at runtime.

All the dependencies get correctly installed when dealing with remote
charts.
If there's a local chart that depends on remote dependencies then those
don't get automatically installed. See #526. They end up with this
error:
```
Error: no cached repository for helm-manager-b6cf96b91af4f01317d185adfbe32610179e5246214be9646a52cb0b86032272 found. (try 'helm repo update'): open /root/.cache/helm/repository/helm-manager-b6cf96b91af4f01317d185adfbe32610179e5246214be9646a52cb0b86032272-index.yaml: no such file or directory
```
One workaround for that would be to add the repositories from the local
charts. Something like this:
```
cd local-chart/ && helm dependency list $dir 2> /dev/null | tail +2 | head -n -1 | awk '{ print "helm repo add " $1 " " $3 }' | while read cmd; do $cmd; done
```
This however is not trivial to parse and implement.
An easier fix which I did here is just to not allow doing
`--skip-refresh` for local repositories.

1. only implement post-renderer flags this patch
2. As mumoshu advise, add helmfile flags `--post-render` and add the
postRenderer config in helmDefaults and release. the priority is
helmfile flags > release > helmDefaults.
3. fix the test case in state_test.go and some other tests.

This improves the `helmfile sync` performance.
From the code: `BuildDeps` is used only by `runHelmDepBuilds`, which
only is used by `PrepareCharts` which is finally only used by
`withPreparedCharts`.
`withPreparedCharts` already does `SyncReposOnce` which means we do not
have to refresh the local repository cache on each chart build.
This is only supported in Helm v3.
This seems to be mostly affecting helmfiles which have a lot of releases
and those release charts use sub dependencies.
I saw significant performance improvements for a helmfile with 45
releases, 2 repositories, and most of the charts also had their own
dependencies. Results:
Before the patch:
* real 9m10.565s
* real 9m38.335s
* real 9m14.941s
* real 5m13.106s (with cache)
After the patch:
* real 6m51.965s
* real 6m36.605s
* real 6m31.685s
* real 3m0.271s (with cache)
These were tested with:
```
rm -rf ~/.cache/helmfile ~/.cache/helm ~/.config/helm/repositories.* && helmfile sync ...
```
The result with `(with cache)` was without deleting the caches first.
From these metrics it seems that the sync duration decreased 20-45%
depending on the run, release count, dependencies and if the cache was
used or not.
As far as I understand, this should be backward-compatible change.
