Changes default log level for salt-call command in the provision script

After this, the invocation can change as -

  provision          # To provision normally
  provision --debug  # Provision with debug info

When the log level is debug, it prints sensitive data on the console (like passwords)
This commit helps avoid that by changing the default log level
