Added dsh management server role, dsh attributes, and dsh groups to
server types
Addresses #1. Management user is now swiftops
dsh/user/admin_user now takes a hash, so one can set and user resource
options they like, including node://swift/dsh/user/uid
Addresses part of #3. Created swift-storage group that is members of
all proxy, account, container, object servers
