Update syslog_json.py

localhost is better than locahost ;)

added vaultfile class for action and lookup plugin usage

should fix #11275

Allow AdHocCLI to be more flexible for overriding

aslo added comment clarifying why we do this

- moved check prompt/password functions to connection, make more senes there
- TODO: consider moving make_become to connection from connection_info
- removed executable param that was never overriden outside of connection info

fixed mixup with remote password vs become_password

- password prompt detection and incorrect passwrod detection to connection info
- sudoable flag to avoid become on none pe'able commands
