Partition.stop: When called, will remove supervisord configuration and update supervisord.
Only started partition has supervisord configuration files.

slapgrid: If `getRequiredComputerPartitionList` fail because or network issue,
buildout cannot process instance. Slapgrid will start any partition that has supervisord configuration
file and exit. This feature is required for `slapos node boot` when computer is offline.

cli.format: parameter `--ignore_network_errors` can be set to ignore exception while
posting xml file to master.

cli.boot: Now call `slapos node format` with `--ignore_network_errors`, then remove
partition timestamp and let cron launch `slapos node instance`. Partition will be
started if there is network issue.

manager.prerm: because of the new behavior of Partition.stop, the rm script
will be killed each time `slapos node report` runs. So the prerm script is
generated in a custom supervisord configuration. Samething for `manager.portredir`.

   This contains external min code, that isnt so complaint with JSL tests

     It is not required to a major test on full scenario to test load parameters from text area, neither 2 tests since it cover both cases as before in a much simpler way.

   Replace tv4 by cfworker json schema and ref-parser

    It was replaced

   As exposed by Romain, `parseFromString` does not throw any error if the XML parsing fails. Instead, you have to manually check if there is a `parsererror` element inside the returned document.
