> At the moment we have 3 types of cancelable "activities".
> # SQL query
> # Transaction
> # Compute job
> Any of these process can be cancelled (killed) using SQL KILL query.
> We need to design and implement a handler (KillQueryHandler?) that will add the ability for external components (TransactionManager, IgniteComputeImpl, etc) to register as a cancellation listener.
> Overall, the cancellation of any such "process" consists of the following steps:
> * if the process is local - cancel it
> * send a message to other cluster nodes to cancel the process
> Note: {{IgniteCompute}} already has a {{cancelAsync}} method for cancelling compute jobs (need to keep in mind how to integrate with it)
