Add support for configuration-based run modes for clush. Run modes are disabled by default because they rely on external tools that we don't want to depend on. They can easily be enabled if needed by installing the corresponding .conf files in clush.conf.d (clush.conf's confdir). sudo support is provided via an example run mode, by defining two variables command_prefix and password_prompt: [mode:sudo] password_prompt: yes command_prefix: /usr/bin/sudo -S -p "''" Then, the sudo mode is activated with --mode or -m: $ clush -w nodes -m sudo command Also added an example of run mode for password-auth based auth with sshpass. Main changes: clush.conf: - add confdir to define paths to config files for run modes - add command_prefix - add password_prompt - removed sudo_command clush.conf.d: - add sshpass.conf.example - add sudo.conf.example clush: - added --mode - removed --sudo Closes cea-hpc#198. Closes cea-hpc#423. Fixes cea-hpc#234.

sudo support is provided via an example run mode, by defining two variables command_prefix and password_prompt:
[mode:sudo]
password_prompt: yes
command_prefix: /usr/bin/sudo -S -p "''"
Then, the sudo mode is activated with --mode or -m:
$ clush -w nodes -m sudo command
Also added an example of run mode for password-auth based auth with sshpass.
