Add ini_setting based custom types for configs

Previous configuration file management method used templates.
This method had limited flexibility and was cumbersome
to use and maintain between upstream versions.

This change introduces new custom types based on ini_setting:
  * swift_account_config: /etc/swift/account-server.conf
  * swift_bench_config: /etc/swift/swift-bench.conf
  * swift_config: /etc/swift/swift.conf
  * swift_container_config: /etc/swift/container-server.conf
  * swift_dispersion_config: /etc/swift/dispersion.conf
  * swift_object_config: /etc/swift/object-server.conf
  * swift_proxy_config: /etc/swift/proxy-server.conf

The use of ini_setting offers multiple advantages:
  * Ability to individually manage configuration settings without
    the need to modify templates. This allows the user to manage or
    override settings that aren't handled by the module.
  * Use upstream default values if none is provided.
  * Remove the need to maintain and synchronize templates
    to match upstream versions. Such maintenance could become
    problematic and complicated if multiple upstream versions
    are supported but have different base configuration files.

Add signing dir

Currently, my swift installation fails with the following
error message:

  [Errno 13] Permission denied: '/root/keystone-signing

and the proxy server can never service requests.

This is b/c by default the client side directory for
pki-signing seems to use $HOME. This commits sets the
directory to be /var/cache/swift/ and resolves my
swift-proxy issues.
