Alexandre Arents be9b735847 Snapshot: offload glance upload in a native thread ...

Execute glance upload in a native thread as it may block the current
coroutine until it completes.

Despite the fact we use eventlet monkey_patching [1] to achieve cooperative
yielding for network IO, file IO on busy file system may still get
nova-compute hanging.

Stick those IO in a native thread using eventlet tpool.execute() [2]
avoid this issue.
