SendPartitionTable packet was sent between Ask and Answer PartitionTable
packets, as notifications. In this case, the only purpose of the 'Answer'
was to check that the partition table was filled. The 'Ask' allowed also
to request a part of the partitions but was not used and redundant with
AskPartitionList for neoctl.

This commit include the following work:
- The partition table is always send in one packet.
- The full partition table is always requested with AskPartitionTable
- The full partition table is notified with SendPartitionTable
- Client node process the answer in the bootstrap handler.
- Admin can receive answer *and* notifications for the partition table.
- Move the log calls to the pt.py module
- Add pt.getRowList() to factorise the code.
- Build partition table packets out of the loop when possible
- Always load inconditionnaly the partition table in generic pt.py
