  - Merge "[Tree-wide] Make chart build process predictible"
  - [Tree-wide] Make chart build process predictible

    ONAP is built using plain makefile rules. List of targets is generated
    using wildcard function. Based on make changelog:

    http://git.savannah.gnu.org/cgit/make.git/tree/NEWS

    since version 3.82 wildcard is not going to sort its results which
    means that charts are being processed in an arbitrary order which may
    lead to build failure due to missing dependencies.

    Since version 4.3 make started sorting the wildcard results once again
    which may lead to build issues.

    To avoid that and make our builds predictible independently from
    Makefile version let's make sure that we always sort wildcard results.

    Addinally let's use 'file://' instead of '@local' for charts in common
    to resolve dependencies between them.
