gPlazma-ldap: fix non-serializable Set problem

reverseMap returned a automatically Scala to Java converted Set class
that did not implement Serializable.  This caused an
NotSerializableException when the object should be send in a cell
message.  This patch adds a couple of manual conversions instead of
automatic ones, ensuring the returned Set is Serializable.

transfermanagers, replica, admin: Fix pool to pool transfers

Addresses problems in transfer managers, replica managers, and the
admin p2p command that prevented these services from starting
pool to pool transfers.

Although CostModuleV1 requires the size field, the above services
don't tunnel the request message through the pool manager and thus
the size field is not strictly required.
