To match the convention of `helm install`, `helm uninstall` is the inverse.

Other tangential changes in this PR:

- StatusDeleting has been changed to StatusUninstalling
- StatusDeleted has been changed to StatusUninstalled
- `helm list --deleted` has been changed to `helm list --uninstalled`
- `helm list --deleting` has been changed to `helm list --uninstalling`
- `helm.DeleteOption` and all delete options have been renamed to `helm.UninstallOption`

I have not made any changes to the "helm.sh/hook-delete-policy", "pre-delete" and "post-delete" hook annotations because

1. it's a major breaking change to existing helm charts, which we've commited to NOT break in Helm 3
2. there is no "helm.sh/hook-install-policy" to pair with "helm.sh/hook-uninstall-policy", so delete still makes sense here

`helm delete` and `helm del` have been added as aliases to `helm uninstall`, so `helm delete` and `helm del` still works as is.

Removes Time, Namespace, and Revision from being exposed to templates to
make template rendering discrete and repeatable.

Resolves #3655
We were seeing that when running helm upgrade with the reuse-values
flag enabled that you could end up in the position where overrides
a.k.a computed values from previous revisions were not being saved on
the updated revision. This left us in a weird position where some
computed values would disappear mysteriously in the abyss. That
happened because computed values from previous revisions weren't merged
with the new computed values every time the reuse-values flag was used.
This PR merges computed values from the previous revisions so you don't
end up in that kind of conundrum.

Cover hook-succeeded, hook-failed and before-hook-creation hook delete policies.
