    Fix strategy amount field validation to support arbitrary objects

    Currently we expect amount field to be an integer, but it can
    also be a string or a YAQL expression. This does not allow us
    to calculate the degree of parallelism for things that should
    be run one by one or in parallel depending on cluster state
    transition
