rest: fix GET /session payload structurev1.2.5-22

Split partition data by client instead of a single array with every
partition.

Old payload structure:
{
  'sessions': [{'disk': 1, 'partition': 1, 'name': 'unknown'}, {'disk': 1, 'partition': 2, 'name': 'unknown'}, {'disk': 1, 'partition': 1, 'name': 'Ubuntu 22.04.4 LTS 64 bits'}]
}

New payload structure:
{
  'sessions': [
     {'addr': '1.1.1.1', 'partitions': ['disk': 1, 'partition': 1, 'name': 'Ubuntu 22.04.4 LTS 64 bits']},
     {'addr': '1.1.1.2', 'partitions': [{'disk': 1, 'partition': 1, 'name': 'unknown'}, {'disk': 1, 'partition': 2, 'name': 'unknown'}]}
  ]
}
