    Refactor CreateDataCenters to use Fields

    so it is consistent with CreateConstraints

    There is a small change of behaviour:
    This does not panic if there is no == or no value following it, but
    ignores the entry instead.

    Allows to specify custom job constraints via the request

    The constraints have to be provided in the format:

    "<attribute> <operator> <value>"

    e.g.

    "${attr.cpu.arch} = arm"

    For compatibility the interpolation notation (`${}`) can be left out and `==` instead of `=` is supported.

    With this implementation the attribute and the operator can not contain
    spaces.
