Changing cache_time doesn't work

[Brant Knudson]

The [assignment].cache_time value is loaded at import-time. This means that it gets the default value rather than the value that the user configured because the user config isn't read until CONF() is called (in keystone-all).

    Fix reading cache-time before configured

    There were several places where the cache time was read at
    import-time. This means that the default value is used rather
    than the value that the user configured because CONF() had not
    been called yet.

    This change makes it so the values are read at run-time, after
    CONF() has been called.

    Don't configure on import

    The keystone.config package called config.configure() at import-
    time.

    This will make it obvious that developers can't use config
    options at import-time because packages that do that will fail on
    import.
