Bryan Boreham 934c520d37 labels: cope with mutating Builder during Range call 
Although we had a different slice, the underlying memory was the same so
any changes meant we could skip some values.

remote.Client: store urlString 
During remote write, we call url.String() twice:
- to add the Endpoint() to the span
- to actually know where whe should send the request

This value does not change over time, and it's not really that
lightweight to calculate. I wrote this simple benchmark:

    func BenchmarkURLString(b *testing.B) {
        u, err := url.Parse("https://remote.write.com/api/v1")
        require.NoError(b, err)

        b.Run("string", func(b *testing.B) {
            count := 0
            for i := 0; i < b.N; i++ {
                count += len(u.String())
            }
        })
    }

And the results are ~200ns/op, 80B/op, 3 allocs/op.

Yes, we're going to go to the network here, which is a huge amount of
resources compared to this, but still, on agents that send 500 requests
per second, that is 1500 wasteful allocations per second.

tsdb: Update OOO min/max time properly after replaying m-map chunks 
Without this fix, if snapshots were enabled, and wbl goes missing
between restarts, then TSDB does not recognize that there are ooo
mmap chunks on disk and we cannot query them until those chunks
are compacted into blocks.

tsdb: Test querying after missing wbl with snapshots enabled 
If the snapshot was enabled with some ooo mmap chunks on disk,
and wbl was removed between restarts, then we should still be able
to query the ooo mmap chunks after a restart. This test shows that
we are not able to query those ooo mmap chunks after a restart
under this situation.

tsdb: Replay m-map chunk only when required 
M-map chunks replayed on startup are discarded if there
was no WAL and no snapshot loaded, because there is no
series created in the Head that it can map to. So only
load m-map chunks from disk if there is either a snapshot
loaded or there is WAL on disk.

Merge pull request #12048 from bboreham/faster-targets 
Scraping targets are synced by creating the full set, then adding/removing any which have changed.
This PR speeds up the process of creating the full set.

I added a benchmark for `TargetsFromGroup`; it uses configuration from a typical Kubernetes SD.

The crux of the change is to do relabeling inside labels.Builder instead of converting to labels.Labels and back again for every rule. The change is broken into several commits for easier review.

This is a breaking change to `scrape.PopulateLabels()`, but `relabel.Process` is left as-is, with a new `relabel.ProcessBuilder` option.
