-----------------------------------------
Summary: Provide API for external components to register itself as
cancellation listener
Key: IGNITE-23440
URL: https://issues.apache.org/jira/browse/IGNITE-23440
Project: Ignite
Issue Type: Improvement
Components: sql
Environment: At the moment we have 3 types of cancelable "entities".
# SQL query
# Transaction
# Compute job
Any of these process can be cancelled (killed) using SQL KILL query.
We need to design and develop a handler API (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
