This provides the capability to specify a project_name,
project_domain_name and user_domain_name in /etc/swift/dispersion.conf.
If this values are set in dispersion.conf they get populated to the
swift-client. With this it is possible to have a specific dispersion
project specified, which is not the keystone default domain. Changes
were applied to swift-dispersion-populate and swift-dispersion-report.
Relevant man pages, the example dispersion.conf and the admin guide were
updated accordingly.
