Starting a collection of Synthetics test examples for learning / teaching purposes

[greatestusername]

This creates a new directory under integrations and such for a library of Synthetics examples. This also provides a space for SA/SE, Customers, etc to provide their own examples. These tests illustrate common flows and concepts that are useful to creating good Synthetic testing.

Currently this includes API Tests and Browser Tests
API:

• graphql-api: Example query of a graphql api and validating the response with JavaScript
• status-page-to-metrics-api: Example querying the status page endpoints for CloudFlare and GitHub then turning those responses into metric timeseries + dimensions and ingesting them to Splunk Observability
• status-to-splunk-hec: Example querying the status page endpoint for OpenAI and sending the details to a Splunk HEC endpoint for ingest
• token-expiration-to-metrics-api: Example query that checks the /organization endpoint of a Splunk Observability organization and sends token expiration metrics to that org for better alerting

Browser:

• hipstershop-complete-order-test-browser: Example Browser interaction simulating a complete user purchase / checkout flow using hipstershop a common demo app for microservices observability
• o11y-login-apm-loading-browser: Example Browser interaction simulating login, navigation to, and validation of data on a specific page in the Splunk Observability APM interface
