This is the fix for only one particular, but important case.
The case when a new resource has been added to the chart and
there is an error in the chart, which leads to release failure.
In this case after first failed release upgrade new resource will be
created in the cluster. On the next release upgrade there will be the error:
`no RESOURCE with the name NAME found` for this newly created resource
from the previous release upgrade.
The root of this problem is in the side effect of the first release process,
Release invariant says: if resouce exists in the kubernetes cluster, then
it should exist in the release storage. But this invariant has been broken
by helm itself -- because helm created new resources as side effect and not
adopted them into release storage.
To maintain release invariant for such case during release upgrade operation
all newly *successfully* created resources will be deleted in the case
of an error in the subsequent resources update.
This behaviour will be enabled only when `--cleanup-on-fail` option used
for `helm upgrade` or `helm rollback`.

There was a typo in a tiller error with "released named" message, I've changed it to "a release named". Also fix a unit-test for it.

Don't delete a resource on upgrade if it is annotated with
helm.io/resource-policy=keep. This can cause data loss for users if the
annotation is ignored (e.g. for a PVC).

Solves #3722 by making the changes in #3539 more compatible with the previous behavior.
This gives a recovery option for "oops I deleted my helm release" by allowing rollback, which is intended to be a working feature of helm. Note that purging releases removes the history required to rollback, so this doesn't work in that case. However, purging takes significantly more time, so it's harder to accidentally purge everything.

Upgrading a release and override existing values doesn't work as expected for nested values. Maps should be merged recursively, but currently maps are treated just like values and replaced at the top level.
If the existing values are:
```yaml
resources:
requests:
cpu: 400m
something: else
```
and an update is done with ```--set=resources.requests.cpu=500m```, it currently ends up as
```yaml
resources:
requests:
cpu: 500m
```
but it should have been
```yaml
resources:
requests:
cpu: 500m
something: else
```
This PR updates the way override values are merged into the existing set of values to merge rather than replace maps.

While investigating a tiller crash on v2.10.0 (see recent comments in #3125), I pulled down the code
and wrote a test replicating the crash I was experiencing. I then
realized that the crash had been fixed, and was able to locate the fix
in #4630 after running a quck bisect.
Since there don't appear to be any tests that cover this crash, and I
had written one myself, I figured I might as well put up a PR for it.
Here's what the test failure on v2.10.0 looks like:
```

* Fix race in helm list when partitioning
Problem:
The chunks slice that is passed through the channel is reused for each
partition. This means that encoding the release into a message is racing with
populating the next partition, causing the results to sometimes not fit in the
message, and the release list to be incorrect
Solution:
Allocate a new slice for each partition

resolves#4337
Merging maps inside of strings gets a bit tricky. When two
strings consisting of "{}" were being added together, this resulted in
"{}\n{}" instead of "{}" which is what we wanted. This led to YAML
parsing errors and showed up when the `--reuse-values` flag was used
when no overrides via `--set` were provided during install and/or
upgrade.
It's really easy to cause an import cycle on this type; this resolves
the problem by moving it out of the tiller pkg into its own. An alias is
left behind in order to prevent downstream breakage.
