iSCSI iqn name RFC violation

[Lucas Alvares Gomes]

The name generated by Ironic for the iSCSI target is violating the RFC 3720 and RFC 3721. Currently the name we generate in Ironic is very simplistic: "iqn-<node UUID>" but this can mess up with some of tools that consumes it (internal folks reported it mess up with the targetcli from Dracut[1]).

    Fix: iSCSI iqn name RFC violation

    Pior to this patch the name generated by Ironic for the iSCSI target was
    violating the RFC 3720 and RFC 3721, and this was messing up with some
    tools consuming it (see deploy-targetcli element for diskimage-builder).

    This patch fixing this generating a name that complies to the RFCs.
