Add service instance name to logs of services

[hlxid]

Description

Currently all log messages from services don't indicate of which service instance they stem.
This can become a problem if you have more than one instance of a service type and a sudden log appears and you don't know which instance is producing it.

To address this ServiceBundle should provide logging methods which prepend the current instance name in front of all messages.
