Invoke a single command on the remote servers. This is useful for performing
one-off commands that may not require a full task to be written for them. Simply
specify the command to execute via the COMMAND environment variable. To execute
the command only on certain roles, specify the ROLES environment variable as a
comma-delimited list of role names. Alternatively, you can specify the HOSTS
environment variable as a comma-delimited list of hostnames to execute the task
on those hosts, explicitly. Lastly, if you want to execute the command via sudo,
specify a non-empty value for the SUDO environment variable.

Sample usage:

  $ cap COMMAND=uptime HOSTS=foo.capistano.test invoke
  $ cap ROLES=app,web SUDO=1 COMMAND="tail -f /var/log/messages" invoke
