Prometheus Alertmanager Icinga Bridge

Changelog

Initial Release after the fork.

Breaking Changes from the original

• Reworked CLI parameters and their environment variables to use the fork's name
• --uuid was renamed to --id since it is not a UUID
• --icinga-url flag does no longer use \n for multiple Icinga endpoints, instead the flag can be used multiple times
• --icinga-ca-file uses a path to a CA certificate file instead of a PEM string
• --debug flag was replaced by --loglevel=debug, loglevels are now passed as: debug, info, warn, error
• --icinga_reconnect flag was removed (for now) might be reintroduced in the future if required
