Make client settings match server settings and improve docs (#189)

[jgitlin-p21]

Description

As described in issue #198, make settings in the client configs (E.G. auth, cipher, compress, etc) match their server counterparts. This eliminates warnings in the OpenVPN log about inconsistent option usage.

In addition, document how the openvpn_user resource works, including showing how additional configuration options can be added to client conf files (using additional_vars and cookbook_user_conf)

New functionality includes testing

I did not write new tests because the openvpn_user resource does not appear to have any tests at all yet 😞 I can work on some, but I won't have bandwidth for a week or more.

Whoops, I broke it 😭 fixing now!
