NIPost validates a NIPost, given a node id and expected challenge. It returns an error if the NIPost is invalid.

Some of the Post metadata fields validation values is ought to eventually be derived from consensus instead of local configuration. If so, their validation should be removed to contextual validation, while still syntactically-validate them here according to locally configured min/max values.
