Allow format to be an object to generate JSON logs. The object keys
become JSON field names, and values support string, variable, and JS.

Note that when there is no JS in the format values, the object will
be pre-serialized to a JSON template string at configuration phase
for better performance.

Example config:
  {
    "access_log": {
      "path": "/tmp/access.log",
      "format": {
        "remote_addr": "$remote_addr",
        "time_local": "$time_local",
        "request_line": "$request_line",
        "status": "$status",
        "body_bytes_sent": "$body_bytes_sent",
        "header_referer": "$header_referer",
        "header_user_agent": "$header_user_agent"
      }
    }
  }

This is a preparatory refactoring for upcoming JSON format support
in access log. We will extend format option to access object for
JSON support.
