Show pretty progressbar when uploading

Registered by Joshua Harlow

It'd be neat if glance client could show a progress bar while uploading. Anvil has something like this and its pretty nifty to have. Obviously it shouldn't be enabled when there is no tty.

Anvil has some code that might be useful...

https://github.com/yahoo/Openstack-Anvil/blob/master/anvil/utils.py#L314 (can be used to show the bar) and https://github.com/yahoo/Openstack-Anvil/blob/master/anvil/shell.py#L220 (can be used to show the transfers that are occurring in junks from one file handle to another - ie a url handle)...
