// URL to send log records to.
//
// An absolute URL, with a scheme. Valid schemes depend on `type`.
// Special schemes `tcp`, `tls`, `udp` and `udps` are used for types that
// have no scheme of their own. For example, to send syslog records using secure UDP:
//
//     \{ type: syslog, url: udps://syslog.example.com:1234 }
//
// Basic TLS is enabled if the URL scheme requires it (for example 'https' or 'tls').
// The 'username@password' part of `url` is ignored.
// Any additional authentication material is in the `secret`.
// See the `secret` field for more details.
//
// Secret for authentication.
// Name of a secret in the same namespace as the cluster logging operator.
//
// For client authentication, set secret keys `tls.crt` and `tls.key` to the client certificate and private key.
//
// To use your own certificate authority, set secret key `ca-bundle.crt`.
//
// Depending on the `type` there may be other secret keys that have meaning.
