Generic driver to map command calls to shell or shell in container calls.

The exporter configuration would look like this:

export:
  power:
    type: jumpstarter.drivers.shell.driver.Shell
    config:
       methods:
          on: "/usr/bin/power on"
          off: "/usr/bin/power off"
          free: "free -h"
          multiline_params: >
             echo "hi,"
             echo "I am a multi-line script"
             echo "I accept parameters ${1} ${2}"

@NickCao, please explain in the description :)

children:
  power:
    type: jumpstarter.drivers.command.driver.Command
    config:
      on: ["./power_on.sh"]
      off: ["./power_off.sh"]

What do you think about making it shell-specific instead, so we could run shell commands instead of
just binaries?

Command makes it look very generic, may be Shell is more specific? WDYT?

Also some additional ideas,so we can pass arguments, and another layer so, later in time
we have room for extensibility (i.e. providing other config arguments like shell interpreter or anything like that)

export:
  power:
    type: jumpstarter.drivers.shell.driver.Shell
    config:
       methods:
          on: "/usr/bin/power on"
          off: "/usr/bin/power off"
          free: "free -h"
          multiline_params: >
             echo "hi,"
             echo "I am a multi-line script"
             echo "I accept parameters ${1} ${2}"
