Change subject: core: End VM export gracefully upon failure in updating OVF
......................................................................


Patch Set 1:

Allon, we indeed need to perform a rollback on that scenario.
Furthermore, we need to fix the audit log if we do go on that direction - the 
user will get an audit log of success while the operation failed (which will 
lead him to think that the export succeeded..a "normal" user might delete the 
original vm after that and lose his data).
.
I'm not sure that we want to fix that issue that way, its rare enough that the 
export fails on the ovf part and it could mean that either something is 
horribly wrong (like the scnario described in the bug) or some other error. if 
we do not want unlimited number of retries we should use the command 
persistency imo to limit the number of retries (it can be a config value), but 
not to try only one time (export of vm can take two days..we copy large amounts 
of data - it might be annoying to start it all over again because of one 
failure to update the ovf).
