Auto deploy corrections for Fuel 9.0

Auto deploy corrections for Fuel 9.0

- The auto deployer's detection of nodes being up corrected as "fuel node"
  now returns "1" instead of "True" to denote that the node is up.

- The location of bootstrap_admin_node.sh has changed so the detection of
  whether the Fuel node installation needed a correction for the deployer
  not to throw an exit code and terminate prematurely.

- Small fix: deploy.py is now executable (just a chmod change).
