…pAuth.*
address https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6329,
makes `reloadAuthKey`, `configAuthKey`, `flagsAuthKey`, `pprofAuthKey`
behavior the same way,
but keys like `-snapshotAuthKey`, `-forceMergeAuthKey` are still
protected by httpAuth.*. All the available key are listed in
https://docs.victoriametrics.com/single-server-victoriametrics/#security.
