request help: How to customize the log file path in apisix-go-plugin-runner

[ZChengjin]

Issue description

As the documentation says I modified the LogOutput of runner.RunnerConfig{} by modifying LogFilePath, but no matter what path I modify LogFilePath to, the log of go-plugin will be printed in apisix_log/error.log in the end.So I want to know How can I customize the log file path in apisix-go-plugin-runner.Thanks

Environment

• APISIX Go Plugin Runner's version:0.50
• APISIX version:3.0.0
• Go version:1.18
• OS (cmd: uname -a):Linux eee3e01b5631 4.19.76-linuxkit ci: enable #1 SMP Tue May 26 11:42:35 UTC 2020 x86_64 GNU/Linux

How do you run the go-runner?

this is my apisix config file:

apisix:
  node_listen: 9080              # APISIX listening port
  enable_ipv6: false

  enable_control: true
  control:
    ip: "0.0.0.0"
    port: 9092

deployment:
  admin:
    allow_admin:               # http://nginx.org/en/docs/http/ngx_http_access_module.html#allow
      - 0.0.0.0/0              # We need to restrict ip access rules for security. 0.0.0.0/0 is for test.

    admin_key:
      - name: "admin"
        key: edd1c9f034335f136f87ad84b625c8f1
        role: admin                 # admin: manage all configuration data

      - name: "viewer"
        key: 4054f7cf07e344346cd3f287985e76a2
        role: viewer

  etcd:
    host:                           # it's possible to define multiple etcd hosts addresses of the same etcd cluster.
      - "http://etcd:2379"          # multiple etcd address
    prefix: "/apisix"               # apisix configurations prefix
    timeout: 30                     # 30 seconds

plugin_attr:
  prometheus:
    export_addr:
      ip: "0.0.0.0"
      port: 9091
ext-plugin:
  cmd: ["/usr/local/apisix/apisix-go-plugin-runner/go-runner", "run"]

I execute make build in my go-runner to generate a binary file, and I copy the binary file to this path:“/usr/local/apisix/apisix-go-plugin-runner“
