'keys' to 'key_conf'

[rohe]

'keys' attribute in configuration file becomes 'key_conf' attribute in Configuration instance.
The reason for this change comes from using the oidcmsg definitions of Configuration as a subclass of dict.
dict already has a method called keys and this caused a conflict.

Bumped version.

let's add a clear message that's it's a btreaking change. Isn't it?

[rohe]

Is it a breaking change ?
It doesn't change the format of the configuration file. It's an internal change to how key information is stored in the Configuration class. Now if you deal directly with the Configuration class instance, not using a file or dictionary as the base, or if you're using a dictionary, you've define, where a Configuration instance is expected then you may be in problem.
