Title: Add --clean options to bundle defaults flags

Prevent building huge gems cache over time.

Since default Capistrano setup is to install gems in shared/bundle cache, I see no use to keep old gems (won't conflict with other deployments using older gems for exemple). I have projects where over a 1 to 2 years period we have build a cache of up to 1-2gb of gems versions.
