v1.4.0

This is the 1.4.0 release of tcmu-runner.

Release notes:

• This is mostly a bug fix release.

The ground work for explicit ALUA support is added but is disabled in this release, because the Red Hat QA team has not tested it and there are still bugs being worked on.

• tcmu-runner is now dual licensed Apache 2 and LGPL v2.

• Ceph support notes:

HA setups should not be done manually with targetcli. The ceph-iscsi-cli tool is the preferred method. Setup and required setting documentation can be found here:

http://docs.ceph.com/docs/master/rbd/iscsi-overview/

• Gluster support notes:

See https://github.com/gluster/gluster-block for gluster tools and instructions that should be used.

• For all other handlers see the README.
