Can't upload image larger than 32GB

By default the max image size that could be uploaded to glance should be 32GB, so you can update this limit with the following command:

cmsh
[shadow-head]% openstack
[shadow-head->openstack[default]]% settingsquota                                              
[shadow-head->openstack[default]->settings:quota]% set maxsingleimagesize 100GB
[shadow-head->openstack*[default*]->settings:quota*]% commit

Can't create snapshots

The problem was due to timeout uploading the image on glance, so we increase this timeout to 120s and change also the defaults from 4s to 20s.
