Is your feature request related to a problem? Please describe.
While we have a new keptn cli option to send a "new artifact" event we currently cant send a new artifact event form an external tool that is not able to interact with the keptn cli.
many tools provide a scripting language to e.g: execute HTTP Requests in order to integrate with external tools. For those tools, e.g: ServiceNow, GitLabs, ... we cant use the keptn cli

Describe the solution you'd like
It would be great to allow sending the cloud native "new-artifact" to the external event broker via HTTPS. that would make integrations with external tools easy!
