Title: Set default debian install_opts to accommodate upgrades.

Without setting this, the cookbook as-is wont accommodate upgrades.
Default behavior of dpkg is to prompt when new package files will
clobber existing package files which have seen changes. While apt
can have a global setting tuned to reflect similar install options,
this just assumes that you want to get to the declared version no
matter what state you might be in previously.
