update to use config.project

resolves “project not defined” error when removing checkpoints
adds check for expected errors resolves #31

When a checkpoint is created or deleted we can ignore processing of
certain errors. (Note lines 532-535 for this commit)
fixes #31. updates storage_limit_exceeded check

Should have been in the creation command, not the deletion command.
import shutil closes #32
return ison from generate_success_response

specifically updated so that the create_apex_checkpoint method in
sfdc_client.py can add an overlayId to the json before returning to the
caller
