Deduplicate Tags / only allow tags to be sent on initial replay event

[JoshFerge]

Right now we send the same tags on replay segments over and over again. we store and index tags in clickhouse, which means we're indexing duplicates of the same data.

We should either use some kind of deduplication logic to not send the same tag twice on replay segments, or alternatively, only send tags on the first segment. I don't think the dedupe logic would be too difficult, could do in memory and that should remove a large % of the duplicated tags.

@JoshFerge Does the backend support tags from non-initial segment? My initial thinking is that we should only send it on the initial segment. It would keep things simpler.

[JoshFerge]

@billyvg right now it does. and yes, I think only sending tags on the initial segment makes sense.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!
