Change schedule priority of daemon/server in config

Code Issues Proposed changes

The goal is to modify schedule priority and I/O scheduling class and
priority of daemon/server via configuration.
Setting is optional, default keeps current behaviour.
Use case:
Prioritize object-server to object-auditor, because all user's requests
needed to be served in peak hours and audit could wait.
