This PR is a preparation to simplify dependency between "exporter"
module and the new "exporterhelper" module that will be created next.

**Description:**
It was suggested that we add the [goleak
package](https://pkg.go.dev/go.uber.org/goleak) to every test in core.
This change adds `goleak` to every package that is succeeds with goleak.
There a number that are not successful, the full list of which I've
posted in the bug.
I generated these files using a shell script to copy a template
`main_test.go` file into each package, then modified the package name.
I'm sure there was a better way to automate this, but it worked well
enough at this point. Here's the script:
```
cp ./main_test.go $1
PACKAGE_NAME=$(basename $1)
sed -i '' -e "s|package component|package $PACKAGE_NAME|g"
$1/main_test.go
pushd . && cd $1 && go mod tidy
go test -v .
```
Usage example:
```
$ ./add_leak_test reciever/scrapererror
```
**Link to tracking Issue:**
#9165
**Testing:**
All added tests are passing, but there are a number failing. Note that there's no sign of `goleak` running until it fails.
