This commit adds support for auto completion for bash and zsh shells. A new root level command called "completion" has been introduced, and the user can get the auto completion code by running `ark completion bash/zsh`. For bash completion, the built-in GenBashCompletion() from cobra has been used, but for zsh, the built-in GenZshCompletion() is known to cause issues. The workaround has been copied from zsh completion code of kubectl. Signed-off-by: Shubham <shubham@linux.com>
