Worker node certificates Script issues

[wasifm]

The script to write out the control and worker car files has the "seq" starting at 1 instead of 0. This results in control0-csr.json not getting created.
Additionally the next step to generate the certificates has a syntax error in the for loop for vmnames array. It should be ${vmnames[@]}

Seems like I wrote these scripts for zsh and forgot to check them on bash. Thanks for reporting.
