    Changed agent reregistration to work with messages directly.

    `reregisterSlave` now accepts `ReregisterSlaveMessage&&`, which opts-out
    of using protobuf arena, and allows passing message through dispatch
    chain without making any copies. Conversion of repeated message fields
    to `std::vector`s is performed only when needed.
