Attributes Processor exercise

Whenever you need to modify attributes of a log, metric or span at the record level you can use the Attributes Processor.

Run the otelcol using prepared config file
```
otelcol-contrib --config config.yaml
```
Read the Attributes Processor documentation
Using the Attributes Processor insert my.custom.attribute attribute with my custom value value. You should see this attribute added to every record:
```
Data point attributes:
   -> my.custom.attribute: STRING(my custom value)
```
