Process statistics data types fixes cf-java-client/issues/1062 and cf-java-client/issues/1063

[keviningvalson]

ProcessStatisticsResource is inconsistent with possible responses from https://v3-apidocs.cloudfoundry.org/version/3.87.0/index.html#the-process-stats-object for processes in a DOWN state

https://github.com/cloudfoundry/cli/blob/master/api/cloudcontroller/ccv3/process_instance.go was referenced for another clients perspective into the data types.

Part of this issue was resolved with a different PR, #1085. I manually merged in the part you have resolving the issue with DOWN state & missing properties. I also added some logic to still perform validation for other states. See 28dea4f.
