This commit introduces an `action` package which allows the consumer to
run Helm actions using the instructions from a `HelmRelease` v2beta2
API object.
The actions do not determine if there is a desire be run, nor do they
record state on the object. This can however be injected by the caller
using the simplified observing Helm storage driver, which now iterates
over a list of callback functions after persisting an object instead
of keeping state.
This separation of concerns would allow e.g. the Flux CLI later on
to run actions (but with a dry-run flag or different storage
configuration) using the object in the same manner as the controller.
Some minor changes have been made to the `postrender` and `runner`
package to allow the code to co-exist while we are inbetween API
versions.

Plus change the tests a tiny bit to work with Gomega, and break the
further API free from direct attachment to our Helm API objects.
