Create a stub to allow the moved ExecutableType to still be imported from FrontendCommon

See: SpiNNakerManchester/SpiNNMan#323

Warning: the warning might occur even when you don't directly import the class.

If this isn't the case, it might be easier to just do "from spinnman.model.enums import ExecutableType", which will immediately make it available here.

Agreed removed.
