[Bug 1722771] [NEW] Connection_info is refreshed on reboot unintentionally

 

Public bug reported:

_get_instance_block_device_info is called without explicitly specifying
'bdms' which is an optional parameter here:
https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L3044

Function definition:
https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L1659

This results in triggering connection_info refresh, which is unnecessary
and also causes problems with implementing the new style attachment
flow.
