OPTIM/MINOR: proxy: do not init proxy management task if unused

Each proxy has its owned task for internal purpose. Currently, it is
only used either by frontends or if a stick-table is present.

This commit rendres the task allocation optional to only the required
case. Thus, it is not allocated anymore for backend only proxies without
stick-table.
