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.

to the origin server.  This change allows that to be tunable, along
with other attributes.

Add in white-list functionality to client auth filter.

Defaulted off. When `node['repose']['client_auth']['uri_regex']`
is true, it lets you bring a regex to bypass client auth filter.
Controlled via `node['repose']['client_auth']['uri_regex']`.
Version bump 2.2.0
