Max attempts while adding runner

* First pass at logic for GHES, not all correct

* Need to mock out file downloading

* Allowed for mocking of HTTP responses

* Added test for builtin GHES action download

* More tests

* Don't retry on action 404

* Remove commented out code

* Add a using statement back, because Windows

* Make windows happy again

* Another windows fix

* Always delete the cache since it isn't fully implemented

* Use RunnerService base class

* Add examples, update URL path

* Remove forceDotCom

* Fix a bug

* Remove a test that's no longer relevant

* PR feedback

* Add missing return

* More trace info

* Use the new agreed-upon format

* Use the auth token since we're hitting GHES directly

* Fixing tests on windows

* Fixed one more test

+# Automate Configuring Self-Hosted Runners
+
+
+## Export PAT
+
+Before running any of these sample scripts, create a GitHub PAT and export it before running the script
+
+```bash
+export RUNNER_CFG_PAT=yourPAT
+```
+
+## Create running as a service
+
+**Scenario**: Run on a machine or VM (not container) which automates:
+
+ - Resolving latest released runner
+ - Download and extract latest
+ - Acquire a registration token
+ - Configure the runner
+ - Run as a systemd (linux) or Launchd (osx) service
+
+:point_right: [Sample script here](../scripts/create-latest-svc.sh) :point_left:
+
+Run as a one-liner. NOTE: replace with yourorg/yourrepo (repo level) or just yourorg (org level) 
+```bash
+curl -s https://raw.githubusercontent.com/actions/runner/automate/scripts/create-latest-svc.sh | bash -s yourorg/yourrepo
+```
+
+## Uninstall running as service 
+
+**Scenario**: Run on a machine or VM (not container) which automates:
+
+ - Stops and uninstalls the systemd (linux) or Launchd (osx) service
+ - Acquires a removal token
+ - Removes the runner
+
+:point_right: [Sample script here](../scripts/remove-svc.sh) :point_left:

+```
+
+### Delete an offline runner
+
+**Scenario**: Deletes a registered runner that is offline:
+
+ - Ensures the runner is offline
+ - Resolves id from name
+ - Deletes the runner
+
+:point_right: [Sample script here](../scripts/delete.sh) :point_left:
+
+Repo level one-liner.  NOTE: replace with yourorg/yourrepo (repo level) or just yourorg (org level) and replace runnername
