Use github.com/klauspost/compress for gzip and zlib
...
klauspost/compress is a high quality drop-in replacement for common Go
compression libraries. Since Prometheus sends out a lot of HTTP requests
that often return compressed output having improved compression
libraries helps to save cpu & memory resources.
On a test Prometheus server I was able to see cpu reduction from 31 to
30 cores.
