Replacing $BASH_SOURCE with ${BASH_SOURCE:-$0} makes devstack zsh friendly: in
bash, $BASH_SOURCE is used per usual; in zsh, where $BASH_SOURCE isn't
defined, $0 is used, which, unlike in bash, evaluates to the current
source file.
Now you can source devstack's openrc from a zsh shell.
Tested with bash and zsh from directories other than the root devstack
directory.

* Remove credential creation from files/keystone_data.sh
* Remove EC2 cert setup from openrc
* Remove sourcing of ec2rc from stackrc
* Collect the above in eucarc
* Allow rc files to be sourced from other directories; based on Chmouel's
4881 proposal but is simpler and doesn't actually change the directory
* Create S3 endpoint
* Get EC2 and S3 endpoints from Keystone service catalog
* Add EC2 credential checks to exercises/client-env.sh
* exercises/bundle.sh and exercises/euca.sh use eucarc
Updates:
