Subject: Do not throw exception on non-integer in snapshot volume_size

A Eucalyptus cloud is returning 'n/a' in the volumeSize field after a
the following setup:
1. euca-create-volume --size 1 --zone $ZONE test1
VOLUME vol-5F220658 1 creating 2010-02-12T21:42:52.872Z
2. euca-create-snapshot vol-5F220658
3. euca-describe-snapshots
invalid literal for int() with base 10: 'n/a'

This changes boto to not raise exception in that case.  volumeSize will
be left as 'None' and the caller will have to address that (euca2ools do
not reference this field at all).

Most correctly, this should probably be fixed in eucalyptus but this
makes boto resilliant to non-integer data in that field.
