Description

Request to add preProcess and postProcess apis to command interface
This would be useful as it would allow developers to break the logic as per the single responsibility principle.
preProcess - to hold logic of initialization, few checks such as connection is fine etc..
execute - main action
postProcess - clean up logic, triggering events based on the outcome of execute

preProcess and postProcess can be done in execute api itself, but sometimes its required to customize only some logic while desiring same action. In that case preProcess() and postProcess() apis can be overriden by the class implementing command interface or extending ChainBase classes
