ref(transactions): dont send transactions to post_process

[JoshFerge]

Once we've deployed #81079, we no longer need to send transactions to post_process.

We delete the redis key from the processing store right in save event as its no longer needed, and take advantage of the existing raw / skip_consume functionality to tell the event stream not to carry on the transaction to post_process after it's been inserted into snuba.

sentry/src/sentry/event_manager.py

Line 1144 in dce58ed

skip_consume=job.get("raw", False),

Once this is merged and the option is turned on, we can delete all of the option code, as well as code that is no longer active in post_process.

part of #81065

note that when this is deployed, there could be some transactions that go through post_process that do not have values in the processing store. this shouldn't cause problems, and wil monitor logs from post_process here:

sentry/src/sentry/tasks/post_process.py

Line 531 in dce58ed

rollout strategy:
#81065 (comment)

[JoshFerge]

TODO: split this up into two separate options as well.

[JoshFerge]

closing this PR as per #81077 (comment), we've decided to not modify post_process as all for this change. deletion from rc processing consolidated into the same option as the rest of the changes.
