Michael McCune d768fbc97d refactoring castellan configuration
This change adds a module for listing configuration options and setting
their defaults. It also changes the key manager base class to
incorporate a configuration during creation. By default, the key manager
will continue to use the global CONF object from the oslo.config
package.

For the most part, this change will be backwards compatible. The one
exception is the creation of sample configuration files. Previously,
importing castellan was sufficient to add these options to the global
configuration object. Now, these options will need to be applied by
using the castellan.options.list_opts function, or adding them through
other means, to create sample configuration files. Similar applies for
setting configuration before instantiating a key manager.

changes
* adding castellan.options with list_opts and set_defaults functions
* changing KeyManager abc to include a configuration option to __init__
* changing barbican and not_implemented key managers to accept
  configuration parameters
* adding tests for set_defaults function
* fixing barbican tests to accomodate new configuration parameter
* adding documentation about configuration usage
* adding castellan configs to oslo entry point in setup.cfg
* adding a genconfig target to tox for producing a sample castellan
  configuration file
* adding the sample configuration file to the git ignore
* renaming barbican option api_version to barbican_api_version
