Proper quoting, error checks, use $KUBE_* variables when applicable, trap to do
cleanup on all errors, call cleanup explicitly on successful exit.
Tested:
- Ran it manually to completion, test run successful.
- Interrupted it during the run, checked that $? was non-zero, etcd was killed.

This doesn't fix anything broken. But we have config-go which exports
KUBE_REPO_ROOT and KUBE_TARGET. Using those means the test scripts can
be more easily moved around the repo and still work. Especially in
hack/test-integration.sh where we use hack/build-go.sh which is going
to use KUBE_TARGET to place the binary, then we use a different method
to find/execute the binary...
add usage
verify flag value for -i is numeric
allow multiple targets on the command line
actually capture coverage output
fix lingering GOFLAGS undef issue
fix issue with -i not working at all: ((x++)) returns 1 when x is 0, which is
incompatible with "set -e"
