add hooks to surround the dj execution in the worker

Add hooks to surround the DJ execution in the worker. This will allow us to configure the environment for each individual Dj. A good use case, when we would like to tag the logs of each Dj bases on an attribute of the DJ.

I think you are looking for the perform callback that already exists

No , I want to prepare the logger for each of the individuals djs , even before the perform callback. so we have the same tag for all log lines, even the ones generated by the worker. and that is why I added it at the beginning of the run method. with this change the below log line will be also affected with the tag.

     job_say job, 'RUNNING'

The perform callback wraps the run call in which you are adding your hooks https://github.com/collectiveidea/delayed_job/pull/1017/files#diff-70ead5838f9d70eb6391b0b682b035fdL312

But I cant define this in my custom job, or at least it is not working as expected.
As I can see you are talking about the hook for the life cycle, however, i would like to add it to the custom job hooks.

Self note: We probably need to re-investigate having the lifecycle callbacks call any appropriate job hooks. Having 2 disjointed setups is not helping our maintainability.
