API Endpoint name should be a slug

[s4nji]

Currently non-URL friendly characters can be used as API endpoint name. This is a problem as they wouldn't be accessible from /apis/API_NAME endpoint.

API endpoint name should be validated and matched against the following pattern:
/^[A-Za-z0-9]+(?:-[A-Za-z0-9]+)*$/

Currently validated against /^[a-z_-]{1,100}$/ in janus-dashboard and revalidated again in janus. Closing.
