Currently only supported authentication methods for CLF in Logging stack are:

• Simple Authentication Security Layer (SASL)
• Username and Password
• Transport Layer Security (TLS)

Many SIEMs, monitoring and external tools are supporting the BEARER token auth strategy (one fine example is Dynatrace).

Is it possible to add BEARER token auth strategy to the Vector CLF[1]?
