Description

At the moment we have 3 types of cancelable "activities".

1. SQL query
2. Transaction
3. 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)
