For the packages that provide helm charts, chartmuseum is used as the local helm chart repository for building the chart, and the port 8879 is used. To avoid race condition, add this bbclass to help adding a lock for do_compile of each package that uses chartmuseum to build helm chart, and add a prefunc to check if the port is already in use by other program on the host.
