The load test creates, copies, proposes and approves `repo-count` repos, each with `package-count` packages with `package-revision-count` package recvisions created for each package. The script initializes or copies each package revision in turn. It adds a pipleline with two "apply-replacements" kpt functions to the Kptfile of each package revision. It updates the package revision, and then proposes and approves the package revision.

The load test script creates repos on the git server at `hostname`, so it's URL will be `http://nephio:secret@hostname:3000/nephio/`. The script expects a git server to be running at that URL.

The `result-file` is a text file containing the time it takes for a package to move from being inititalized or copied to being approved. It also records the time it takes to propse-delete and delete wach package revision.

The `repo-result-file` is a csv file that tabulizes the results from `result-file` into colums for each repo created.

For example:

```bash
porch % scripts/run-load-test.sh -s 172.18.255.200 -r 4 -p 2 -e 3
running scalability test towards git server http://nephio:[email protected]:3000/nephio/
running load test towards git server http://nephio:[email protected]:3000/nephio/
4 repos will be created
2 packages in each repo
3 pacakge revisions in each package
results will be stored in "scalability_results.txt"
repo results will be stored in "scalability_repo_results.csv"
the log will be stored in "scalability.log"
scalability test towards git server http://nephio:[email protected]:3000/nephio/ completed
results will be stored in "load_test_results.txt"
repo results will be stored in "load_test_repo_results.csv"
the log will be stored in "load_test.log"
load test towards git server http://nephio:[email protected]:3000/nephio/ completed
```

In the load test above, a total of 24 package revisions were created and deleted.
