Add shell run and output commands

Opengnsys needs a support to execute commands on the machine. This patch adds
the support for executing two new commands "shell/run" and "shell/output". The
first one, give us the support for executing a command in the machine and keep
save in a queue the output. The second one, give us the support for sending the
output from the command executed.
