Remove HTTP library

Remove HTTP library

The library is old and does not work with python3. It appears
that the *** Settings *** section in the affected files may
have just been copy/paste from the same source and likely the
library is not used. It's possible that some tests would break
if the library was being used. In that case, things will have
to be ported to the more commonly used RequetsLibrary keywords.
