Hot templates output is not used in the unit tests

[Simeon Monov]

For the unit tests that we have a generated HOT output under data/hot_output, it should be used to compare the resulted output from the unit test.

    Create a unit test for wordpress specification in TOSCA

    Create a TOSCA-HOT translation unit test template and use that to
    unit test TOSCA wordpress example.

    Note, to implement this patch some changes had to be made to the
    wordpress TOSCA file as translation of certain pieces were not fully
    supported, as described in bug #1440247. As a result of the change in
    wordpress TOSCA file some existing test cases had to be skipped as
    well. It is important to re-enable the skipped code and revert the
    changes made to wordpress TOSCA file as part of bug #1440247 patch.

    Also, shell scripts that support mysql, web server, and wordpress
    installation and configuration were also updated to make sure the
    HOT translation works with the ubuntu-software-config-os-init image.

    To address bug #1447800 handling of null dictionaries was also
    improved.
