default of OPENSTACK_KEYSTONE_DEFAULT_ROLE still "Member"

[Akihiro Motoki]

In bug 1264228 and https://review.openstack.org/#/c/64137/, the default value of OPENSTACK_KEYSTONE_DEFAULT_ROLE was changed from "Member" to "_member_" which is the default config value in keystone.

However, OPENSTACK_KEYSTONE_DEFAULT_ROLE in openstack_dashboard/settings.py is not changed and it is the default value.
It should be updated too.

It is better to be fixed before Icehouse release for consistency.

    local_settings.py and the document from "Member" to "_member_"
    which is the default config value in keystone.
