Bad EC2 tokens with Euca Tools gives incorrect error

[Navraj Chohan]

I tried to set my environment variables with new credentials and then use euca tools to start a EC2 cloud. I choose a keyname which was never used before. The tools complained that the tools need to be deleted first, but in fact the problem was because my credentials were not valid (Amazon somehow deleted my access key and secret key). What the tools should do is report the correct error.

About to start AppScale over a cloud environment with the euca tools with instance type m1.large.
The keyname you chose is already in the system. Please either run this tool again with the --force flag or run the following:
euca-delete-keypair appscaleRaj543

Me running it forced:
