/**
* This task removes service assembly from state holder file.
*
*
* This task MUST be executed with a {@link Context} containing:
*
* - service assembly name as entity name
* - archive URL
* - install URL
*
* and returns following data in the {@link Context}:
*
* - the service assembly state holder ({@link ServiceAssembly}).
*
*
* The task has a non-robust approach: it tries to do all the subtasks and
* doesn't have the undo capability.
