Subject: [PATCH] Demonstrate how to set the Resource for LogEmitterProvider
 (#2209)

* Demonstrate how to set the Resource for LogEmitterProvider

Added a Resource to the logs example to make it more complete.
Previously it was using the built-in Resource. Now it adds the
service.name and service.instance.id attributes.

The resulting emitted log records look like this:
```
Resource labels:
     -> telemetry.sdk.language: STRING(python)
     -> telemetry.sdk.name: STRING(opentelemetry)
     -> telemetry.sdk.version: STRING(1.5.0)
     -> service.name: STRING(shoppingcart)
     -> service.instance.id: STRING(instance-12)
InstrumentationLibraryLogs #0
InstrumentationLibrary __main__ 0.1
LogRecord #0
Timestamp: 2021-10-14 18:33:43.425820928 +0000 UTC
Severity: ERROR
ShortName:
Body: Hyderabad, we have a major problem.
