    libvirt: Always escape IPv6 addresses when used in migration URI
    
    If IPv6 is passed to URI it should be wrapped within square brackets.
    This patch detects IPv6 to form migration URI properly. Domain name, IPv4 or
    already bracketed IPv6 address will pass as is
    
    Extend tests to include collapsed IPv6 addresses and IPv6 addresses with
    port

Title:
  Live migration failed: Unable to parse URI
  qemu+ssh://nova_migration@fd00:

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Unable to parse URI
  qemu+ssh://nova_migration@fd00:fd00:fd00:2000::1e/system?keyfile=/etc/nova/migration/identity

  IPv6 URI should be wrapped in [], to avoid ambiguity wrt port number.

  nova/virt/libvirt/driver.py needs some logic to wrap IPv6 addresses to
  brackets. Otherwise live migration will fail due to malformed URI
