fixed the issue with setting tracing and metrics options with env variables

[prasadmadanayake]

📝 Description

When using the runner we cannot set tracing options using env variable because defaultOption tracing is a boolean and runner only update the values if property is an object

moleculer/src/utils.js

Line 409 in 5d72c97

if (typeof obj[part] !== "object") {

So the fix is created by changing the tracing and metrics property to object with default state as false
