Create fragments for managing keystone.conf

This commit introduces fragments to manage
the keystone.conf file.

It introduces the following templates that can
be used to manage part of the final keystone file
  - footer (things that dont need to be configured)
  - sqlite - configures db as sqlite
  - mysql - configures db as mysql
  - identity - manages the identity used
  - ldap - adds ldap snippet
  - default - DEFAULT config section
  - sql_catalog - adds sql catalog support
  - template_catalog - adds template support for
    catalogs

The templates can be assembled using keystone::config
into a customizable final template.
