This commit moves the generated-resources directory to be within
the build directory for the openldap-tests and saml-idp-tests
projects. Both projects create a generated-resources directory that
should have been in the build directory but were instead at the same
level as the build directory.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
