LU-7988 hsm: update many cookie status at once

LU-7988 hsm: update many cookie status at once

Instead of calling mdt_agent_record_update, which calls
cdt_llog_process, once for every HAL, build a list of the cookies to
update with their status and call mdt_agent_record_update just once
per seconds at most.

Update mdt_agent_record_update to take a status for every cookie.
