Reimplemented snapshot mechanims & redesigned drivers & resource interfaces

[sparshev]

The change is quite big due to alot of design flaws was rethought. In general it adds ApplicationTask struct, but also seriously changed the driver & resource structs & interfaces.

• Added when field to ApplicationTask to specify when to execute task - especially useful for snapshot to execute before DEALLOCATE
• Moved ApplicationStatus aside to use in ApplicationTask when field
• Redesigned Resource to put identifier field in it in order to use hwaddr only by it's direct purpose.
• The driver Allocate/Status/Deallocate interfaces was moved to direct use of Resource instead of basic types - I think it's much more convenient, because we would not need to change interfaces much and they will be much more stable in time. Drivers would be able to use struct fields and if we adding a new one it's not a big deal for them.
• Added task and resource info to the task execution
• AWS: Now sets friendly name for the instance
• VMX: Now uses vmx path as the primary resources identifier
• Clarified the CI workflow info & added xml report
