Łukasz Mierzwa	3196c98bc2	Reduce memSeries memory usage by decoupling metadata (#11152 ) Metadata was added recently but doesn't seem to be used much, at least as far as I could identify. Yet it's part of memSeries struct and so even when empty takes 48 bytes, which is a lot given that without it memSeries requires 224 bytes. This change turns it into a pointer on the struct, that get set only when metadata is actually set of given series.

When checking for cache entries though, we used p.Series() as the key, which included the metric name _with_ its labels. That meant that we were never actually hitting the cache. We're fixing this by utiling the __name__ internal label for correctly getting the cache entries after they've been set by setHelp(), setType() or setUnit().

Peter Štibraný	ffc60d8397	Reduce chunk write queue memory usage 2 (#10874 ) * Job queue This PR reimplements chan chunkWriteJob with custom buffered queue that should use less memory, because it doesn't preallocate entire buffer for maximum queue size at once. Instead it allocates individual "segments" with smaller size. As elements are added to the queue, they fill individual segments. When elements are removed from the queue (and segments), empty segments can be thrown away. This doesn't change memory usage of the queue when it's full, but should decrease its memory footprint when it's empty (queue will keep max 1 segment in such case).

Matthias Rampke	78f2645787	test(tsdb): break up repeated test to avoid timeout (#10671 ) On macOS, the TestTombstoneCleanRetentionLimitsRace performs very poorly. It takes more than a second to write out one block, and as it writes 400 of them, we run into the 10-minute test timeout frequently. While this doesn't fix the actual performance issue, breaking each iteration into a subtest makes the test pass reliably (because each iteration comfortably finishes in under a minute).
