feat(tracing): refactor tracing

[vm-001]

Summary

• The configuration tracing.enabled is replaced by tracing.instrumentations(defaults to []).
• Make tracing tests easier to test.
• Set different timeouts for different services. The maximum graceful shutdown timeout for application is 30 seconds.
• Add trace_id field to access log (only for JSON format).
• Refactor Plugin.

Configuration

  instrumentations: []                          # The list of enabled tracing instrumentations.
                                                # By default, no instrumentations are enabled.
                                                # Supported values are:
                                                # - `request`: HTTP request instrumentation.
                                                # - `plugin`: Plugin instrumentation.
                                                # - `dao`: DAO instrumentation.
                                                # - `@all`: an alias of all instrumentations.
