take care with Scientific Linux and  case where lsb_release is installed...

... on centos or scientific linux
file bootstrap
   if lsb_release is installed, bootstrap does not  test /etc/redhat-release (fix it)
 and if lsb_release is no installed: take care  of Scientifc linux in the list of supported os.
 file vendor.py (remoto installation)
 setup failed because of  ceph.com url (fix it)


 I have an  error  when it try to run git clone git://ceph.com/remoto
It is like repository doesnt exists, that is why I looking for another repository.
