a few things were missing for it to work:
* on the cli, we have to get the option as an array if the type is an
array
* the untainting must be done recursively, otherwise, the regex matching
converts an array hash into the string 'ARRAY(0x123412341234)'
* JSONSchema::parse_config did not handle array formats specially, but
we want to allow to specify them multiple time
* the biggest point: in the RESTHandler, to be compatible with the
current gui behavior, we have to rewrite two parameter types:
- when the api defines a '-list' format for a string type, but we get
a list (because of the changes in http-server), we join the list
with a comma into a string
- when the api defines an 'array' type, but we get a scalar value,
wrap the value in an array (because for www-form-urlencoded, you
cannot send an array with a single value) add tests for this
behavior, some of which we want to deprecate and remove in the
future
