Add missing octopus -> pacific upgrade path

The octopus -> pacific upgrade path is missing from the stable/pacific
branch, which results in an error and failure to upgrade.

Invalid upgrade path from octopus to octopus. Valid paths are: ['firefly
-> hammer', 'hammer -> jewel', 'jewel -> luminous', 'luminous -> mimic',
'mimic -> nautilus', 'nautilus -> octopus']
