linstor-gateway v1.4.0

Hello,

we have just released LINSTOR Gateway v1.4.0.

https://github.com/LINBIT/linstor-gateway/releases/tag/v1.4.0

As there were no reported problems with the release candidate, there
were no further changes since rc1.

Here is the changelog again, as a reminder:

### Features

* The `nfs create` command now supports creating multiple NFS exports in
the same cluster. (6244defb)
* The `delete` command now prompts for confirmation before deleting a
resource. (7c6d7833)
* drbd-reactor configuration files generated by LINSTOR Gateway are now
versioned and can be migrated to new versions automatically. (87230226,
f72c2c39)

### Fixes

* The `nfs upgrade` command now actually respects the `--dry-run` flag.
(e760b419)
* drbd-reactor configuration files no longer include the deprecated `id`
field. (878d53f4)
* In the NFS configuration file, the `IPaddr2` and `nfsserver` resource
agent entries were switched. These are now in the correct order. (2337e327)
