Create implicit logging scopes from Activity.Tags

[shirhatti]

Builds upon the work in #34305

This is a proposal to implicitly flow Activity.Tags to ILogger scopes by creating implicit logging scopes from Activity.Tags. Based on our offline discussion, we'll need to add an option to turn this on/off.

There is currently no consensus on whether this should be on by default.

In we decided not to do this, we'll at least need to provide guidance on the idiomatic way to do this.

In the 5.0 timeframe, we'll provide guidance via docs on how to do this. We may reconsider in the future.

We are not going to provide this feature for now until we see a demand on it.

In we decided not to do this, we'll at least need to provide guidance on the idiomatic way to do this.

So therefore the next step for this issue is to provide documentation on adding Activity.Tags to logging.

@shirhatti @tarekgh @noahfalk do you have any update on this? Should it be considered for 6.0?

[tarekgh]

@ericstj we already have #46571 which is the feature requested currently marked for 6.0. I believe if we implement the requested feature will address the question in this issue. basically it will be opt-in choice to include the Tags (and the Baggage). We still discussing the feature though.

This is taken care of by the #48722
