This is part of HIP 20 which provides a means to have v3 charts
that live alongside v2 charts while having breaking changes.
The plan is to have a different release object for v3 chart
instances for at least a couple reasons:
1. So that the chart object on the release can be fundamentally
different.
2. So that Helm v3 does not detect or try to work with instances
of charts whose apiVersion it does not know about.
Note: it is expected that Helm v3 usage will be used long after
the Helm project no longer supports it. 5 years after Helm v2
had reached end-of-life there was still usage of it.
Note: The release util package is separate from the versioned
elements as it is planned to use generics to handle multiple
release object versions.

Since Helm is going through breaking changes with Helm v4, the version path to
Helm needs to be updated.

This adds a new configuration option to Tiller to limit the number of
records stored per release.
Tiller stores historical release information (helm history, helm
rollback). This makes it possible to set a maximum number of versions
per release.
To enable this feature, use `helm init --history-max NNN`. Note that
because of the restrictions on Deployment objects, you will have to
re-install Tiller to add a limit.
Along the way, I found an unreported bug in the Memory storage driver.
This fixes that bug and adds substantially more tests to catch
regressions.
Closes#2332
