OPENSTACK_KEYSTONE_DEFAULT_ROLE is not correct by default

[JiaHao Li]

keystone default role is _member_, while horizon set OPENSTACK_KEYSTONE_DEFAULT_ROLE to Member. So if operator follows the instruction of docs.openstack.org installation guide, then he/she will fail to create new project on dashboard->admin->project->create project.

It is really user friendly to modify default value to _member_ to sync with keystone default setting

NOTE: this also affect havana branch

    Sync OPENSTACK_KEYSTONE_DEFAULT_ROLE with keystone

    For now, keystone default role is _member_, while horizon set
    OPENSTACK_KEYSTONE_DEFAULT_ROLE to Member. It will really be user
    friendly to modify horizon default value to _member_ to sync with
    keystone's default setting.
