Switch winston to pino

[hongbo-miao]

For logging libraries supporting transports, I feel I am just sold by this pino benchmark. https://github.com/pinojs/pino/blob/master/docs/benchmarks.md
And it supports async too!
It also supports redact, using fast-redact internally (fastest redact library I found, I was planning to use with existing winston actually)

For middleware level, pino-http, can reach 21496 req/sec, 25770.91 req/sec (extreme)
