* Adds development instructions to README
* Replaces deprecated io/ioutil with io package
* Catch all thrown errors and handle them.
- not catching errors could result in unknown behaviour
* Fix gofmt formatting issues
* Refactor to allow http client to be provided
- default client does not have timeout etc., we may instead wish to provide a custom http client.
* Refactor to something closer to the standard go layout
- separates alert forwarder into separate package to allow for testing/reuse
* Split out types, and split Discord client into its own package
* Renaming of symbols for readability
- no need to abbreviate words in modern IDEs
* remove go-vet hook as it is broken when go files are not in root directory
* unit tests for ~90% coverage
* Update picture in README
* Return error status codes to caller in event of error from Discord
* Remove panic, replace with error status code response and log message. Improve the status codes that are returned to provide more context on what has occurred.
* Graceful shutdown of server, including signal handling
* Integration tests
- mocks Discord server
- tests Happy case and a couple of unhappy cases
- most edge conditions are otherwise tested in unit tests
* CheckWebHook should return errors instead of logging
- additional checks in tests for nil objects
- attempt to solve integration test pollution by using different port numbers to prevent potential collision
- Temporarily comment out test causing interaction pollution with other tests
* structured logging
* feat(exponential backoff): Added to Discord client
* Serve prometheus metrics
- Monitoring for the discord client
* adds correlation ID to logging
* refactors the mock http client to allow it to work with instrumentation for monitoring
* Helm chart service monitor
* Improved flag and env var parsing
* Application version passed in via build args
* Order of precedence of configuration configuration file<environment variable<command line
* Mounts secret to file instead of in environment variable
* Adds build tag to integration tests to prevent them being run as a unit test
