Gorka Eguileor f67d46c538 Add open-iscsi manual scan support
It was recently added to open-iscsi the functionality to disable
automatic LUN scans on iscsid start, on login, and on reception of
AEN/AER messages reporting LUN data has changed.

Those 3 cases were one of the causes why Nova-CPU and Cinder-Volumes
nodes would have unexpected devices.  With this new feature we can
prevent them from appearing unnexpectedly.

This patch adds the mechanism required to configure our sessions for
manual scans in a backward compatible way.

Manual scans are enabled setting `node.session.scan` to `manual`.

features:
- |
Support for setting the scan mode on the Open-iSCSI initiator. If
installed iscsiadm supports this feature OS-Brick will set all it's new
sessions to manual scan.
fixes:
- |
On systems with scan mode support on open-iSCSI we'll no longer see
unwanted devices polluting our system due to the automatic initiator scan
or to AEN/AER messages from the backend.
