Dynamic target for logging

[Braqzen]

Feature Request

Motivation

I should be able to do

info!(target: some_variable);

additionally it would be nice to set the target globally so each log doesn't have to pass it in.

Being able to pass in a value enables custom targets in libraries rather than hard coding for each case.

Does it have to be target? Why not add a different attribute which can be added to a span?

It appears that target is the correct way to do it.
Iirc you may also turn the target off when creating a subscriber but then it displays <log leve> trace instead.

It would be nice to have a dynamic <level> TARGET ....

Wanted to upvote this issue for future efforts!
I found that when having a core application integrate with the logs of plugin applications not being able to edit the original target of the plugin logs is a challenge.
