Motivation
Regression of #11681
In case of standalone functions worker, the pulsar client connected to the broker doesn't pick up the
brokerClientTrustCertsFilePathconfiguration if authentication is disabled.This causes issues if
TlsEnableHostnameVerification=trueand the certificate is self signed.I don't think is much critical since non authenticated clusters are very rare when tls is enabled.
