      We have discussion on the unit of Allocation rate. https://mail.openjdk.java.net/pipermail/jmc-dev/2022-April/004614.html

      Marcus comments that JFR already has compound units:
      eg.
        <XmlContentType name="bytes-per-second" annotation="jdk.jfr.DataAmount(BYTES), jdk.jfr.Frequency" />
        <XmlContentType name="bits-per-second" annotation="jdk.jfr.DataAmount(BITS), jdk.jfr.Frequency" />

      bytes-per-second is referred by event G1BasicIHOP.

      bits-per-second is used by NetworkUtilization

      We need to support a subclass of IUnit which supports compound unit.
