Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Make simple _over_time functions range aware Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Reduce allocs when working with matrix selectors Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Add basic benchmark for range evaluation Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Reuse objects for function arguments Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Do dropmetricname and allocating output vector only once. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Add range-aware support for range vector functions with params Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Optimise holt_winters, cut cpu and allocs by ~25% Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Make rate&friends range aware Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Make more functions range aware.

Load only some offsets into the symbol table into memory. Rather than keeping the entire symbol table in memory, keep every nth offset and walk from there to the entry we need. This ends up slightly slower, ~360ms per 1M series returned from PostingsForMatchers which is not much considering the rest of the CPU such a query would go on to use. Make LabelValues use the postings tables, rather than having to do symbol lookups. Use yoloString, as PostingsForMatchers doesn't need the strings to stick around and adjust the API call to keep the Querier open until it's all marshalled. Remove allocatedSymbols memory optimisation, we no longer keep all the symbol strings in heap memory. Remove LabelValuesFor and LabelIndices, they're dead code. Ensure we've still tests for label indices, and add missing test that we can work with old V1 Format index files. PostingForMatchers performance is slightly better, with a big drop in allocation counts due to using yoloString for LabelValues: benchmark old ns/op new ns/op delta

Don't sort postings if we only have one block. Sorting the heads postings can be quite slow. We only need sorted series when merging with another querier, so only sort then. This will make big queries that only touch the head faster, though queries that touch both the head and a block will still be the same speed. This probably won't help much with graphing unless the range is under an hour, however it should make most recording rules faster. Add gaurantee that remote read streaming produces sorted series.
