Proposal: Matches with the fluent bit log format.

[k-kinzal]

Problem

There is a difference in the output format between fluent bit and fluent bit go s3.

fluent bit log

[2020/04/13 09:41:04] [ info] [engine] started (pid=1)

fluent bit go s3

time="2020-04-13T09:41:04Z" level=info msg="[flb-go 0] Starting fluent-bit-go-s3: (version=0.7.0, branch=HEAD, revision=e8a6673)"

This is not a big problem, but it does complicate the parsing of the log.

So I would like to change the format of the log, how about that?

Steps to replicate

None. This is feature request.

Expected Behavior or What you need to ask

...

Using Fluentd and S3 plugin versions

• OS version
• Bare Metal or within Docker or Kubernetes or others?
• fluent-bit version
  • paste result of fluent-bit --version or td-agent-bin --version
• fluent-bit-go-s3 version
  • paste boot log of fluent-bit or td-agent-bit

fluent-bit-go-s3 uses logrus for logger. logrus seems to support customizing logging format. https://github.com/sirupsen/logrus#formatters
