Brian Cain 432cb8d915 (#7826) Add salt_arg option for passing flags to salt tool
This commit introduces the salt_arg option that allows a user to pass
additional command line flags to the `salt` tool when provisioning with
a master setup.

It also adds additional config validation to ensure that both
`salt_args` and `salt_call_args` is an array.
