stx-chartmuseum: add new bbclass

Browse Source 
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.
