Validate command on something else than return code

[wilfriedroset]

Currently Milkcheck validate a service using the return code of the command. It would be simplier to be able to validate a command by its output:

• match strings, regex (match or doesn't match)
• float or int (greater, lesser, equal than)

The current workaround would be to use test in the command.

linpack:
    target: "@compute"
    actions:
        bench: 
            cmd: /some/path/linpack
            validate: float
            value: >= %LINPACK_MIN_VALUE
check_bios:
    target: "@compute"
    actions:
        status:
            cmd: dmidecode -t bios | awk '/Version/{print $NF}'
            validate: string
            value: %BIOS_VER

It is easy to workaround this using bash constructs for now. Low priority ticket.
