Add GitHub Enterprise Server support

Enable CDash to post check runs and commit statuses to ghe installations
in addition to github.com.

Changes:
- Add GITHUB_ENTERPRISE_URL config option (env var)
- Pass enterprise URL to GitHubClient constructor with apiVersion=null
  (so it defaults to 'v3') so the PathPrepend plugin builds correct
  /api/v3/ paths for ghe
- Add isGitHubUrl() helpers in GitHub.php and RepositoryUtils.php to
  match repository URLs against both github.com and the configured GHE
  host
- Convert get_github_api_url() to construct /api/v3/repos/ paths for GHE
  repositories
- Make DoneHandler always create/update the check when a revision exists,
  rather than requiring the pendingSubmissions recheck flag
