[Helm Integration] Evaluate if we need to store unpacked bundles in cache.

[varshaprasad96]

Operator controller currently implements the store interface from Rukpak, using a localdir, to so store unpacked contents.
Evaluate if this is required after changing the unpack to use directly registry client.

Is this done?

This is not done. I'm pretty sure we store the unpacked bundles twice. Once in an unpacker cache and once in the Storage implementation.
