Remove Plugins that re installed but not listed in the playbook.

[gingerwizard]

Currently if the user does the following:

1. Installs ES with plugins
2. Changes the plugins listed - adds and removed
3. Re-runs the playbook

The plugins are not changed to those in step (2) - they are required to specify es_plugins_reinstall:true. My current proposal is to remove all plugins and re-install them in the event of ANY delta.

@jakommo thoughts?

I'm 👍 on "remove all plugins and re-install them in the event of ANY delta."

@jakommo i have a PR ready which would correct deltas. What was our reasoning (my bad memory) for removing ALL in the event of a delta?

#269 should resolve
