Reorder lib files removing redundant dir layer

Move all the files of 'cns-libs/cnslibs/common' dir
to the 'openshift-storage-libs/openshiftstoragelibs',
because 'common' is the only dir there, which doesn't really makes sense.
And "cns" is old project name, so, replace it with
"openshift-storage-libs".

Also, fix all the imports of these libs.
