/**
* The endpoint encapsulates portions of the GitHub API, relying on the org.eclipse.egit.github.core Java SDK.
* Available endpoint URIs include:
*
* CONSUMERS
* github://pullRequest (new pull requests)
* github://pullRequestComment (new pull request comments)
* github://commit/[branch] (new commits)
* github://tag (new tags)
*
* PRODUCERS
* github://pullRequestComment (create a new pull request comment; see PullRequestCommentProducer for header requirements)
*
* The endpoints will respond with org.eclipse.egit.github.core-provided POJOs (PullRequest, CommitComment,
* RepositoryTag, RepositoryCommit, etc.)
*
* Note: Rather than webhooks, this endpoint relies on simple polling. Reasons include:
* - concerned about reliability/stability if this somehow relied on an exposed, embedded server (Jetty?)
* - the types of payloads we're polling aren't typically large (plus, paging is available in the API)
* - need to support apps running somewhere not publicly accessible where a webhook would fail
