Vlad Zolotarov 3a54bab193 controller: update get_client_data to use foreign_ptr for client_data ...

get_client_data() is used to assemble `client_data` objects from each connection
on each CPU in the context of generation of the `system.clients` virtual table data.

After collected, `client_data` objects were std::moved and arranged into a
different structure to match the table's sorting requirements.

This didn't allow having not-cross-shard-movable objects as fields in the `client_data`,
e.g. lw_shared_ptr objects.

Since we are planning to add such fields to `client_data` in following patches this patch
is solving the limitation above by making get_client_data() return `foreign_ptr<std::unique_ptr<client_data>>`
objects instead of naked `client_data` ones.
