Fixed issues reported by test-style

The current methodology generated its own RS slice instead of using
a helper method that uses a `clientset`. This caused some issues where
`FindNewReplicaSet` always returned `nil`. This switches the method and
removes some unneeded API calls and code.

Closes #2426

Fix minor typo in test doc

Fixes various issues related to plugin command

Fixes issues/2398 - helm plugin remove does not works as expected

- [ ] plugin remove option is coded to remove multiple plugins, but instead returns error when more than one plugin is requested to be removed.
- [ ] plugin remove does not show any error/message for non-existent plugin.

Partially fixes issues/2385 - helm install silently updates the plugin, if it pre-existed

Fixes issues/2384 - helm plugin install installs a default version in case requested version is not available
