Brought the existing Isolator code base up from version 0.23.X to 0.24.X.

Notable changes:
* IsolatorProcess class has been deprecated. Must implement and extend the Isolator class
* In receover() the object being passed in was of type ExecutorRunState but now it is of type ContainerState. The implement is similar but has some subtle differences
* In prepare(), the const Option<std::string>& rootfs parameter is no longer being passed into the function
