Lifted completely from helm, no changes other that removing
autocompletion as we dont have that yet

Instead of using directly the helmCli settings
use our own composite type

Picks the name from the chart based of Annotations then
falls back to the default name in the chart.yaml
This allows us to only pass the chart path to upgrade.
If this is called on a new chart install also works as
expected by setting the chartname before calling install

Allows to override the release name via a flag
--release-name STRING which will ignore any
annotations or names in the chart.yml file

Adds the ReleaseName field to the hypper Upgrade struct
to keep track of the release name.

Works both on Upgrade and NewInstall

As we automatically obtaine the release name, the upgrade
tests needs some small fixes to work as expected

 - Use composite type for History
 - Fix comments that refer to upgrade name
 - Missing doc comments
 - Missing license header
