[VM/PublicIP] Fix: Resolve default-PublicIP assign/unassign bugs across AWS/NCP/KT/OpenStack/NHN

[powerkimhub]

• Add assign-publicip-true test suite (true→false→true lifecycle), mirroring assign-publicip-false, across all 10 CSPs
• Fix AWS RemoveDefaultPublicIP AuthFailure caused by an unnormalized "Not set" StsToken sentinel
• Fix NCP RemoveDefaultPublicIP 400 error: match by ServerInstanceNo instead of a bogus ServerName, and wait for the PublicIP's async state to settle before Disassociate/Delete
• Fix KT resolveVMPrivateIP: replace the unreliable ports.List call with the existing GetVM()-based lookup
• Fix OpenStack/NHN GetVM: clear PublicIP when the live floating-IP lookup finds nothing, instead of leaving a stale value
• Add read-after-write wait in common-runtime's AssignVMDefaultPublicIP so a just-assigned PublicIP is reliably visible on the next GetVM
• Fix test script to preserve already-captured PrivateIP/PublicIP/SSH fields on later-step failures instead of blanking them
