Raphael S. Carvalho 74ecedfb5c replica: Fail timed-out single-key read on cleaned up tablet replica
Consider the following:
1) single-key read starts, blocks on replica e.g. waiting for memory.
2) the same replica is migrated away
3) single-key read expires, coordinator abandons it, releases erm.
4) migration advances to cleanup stage, barrier doesn't wait on
   timed-out read
5) compaction group of the replica is deallocated on cleanup
6) that single-key resumes, but doesn't find sstable set (post cleanup)
7) with abort-on-internal-error turned on, node crashes

It's fine for abandoned (= timed out) reads to fail, since the
coordinator is gone.
For active reads (non timed out), the barrier will wait for them
since their coordinator holds erm.
This solution consists of failing reads which underlying tablet
replica has been cleaned up, by just converting internal error
to plain exception.

Fixes #26229.

Scylla in-source tests.

For details on how to run the tests, see docs/dev/testing.md

Shared C++ utils, libraries are in lib/, for Python - pylib/

alternator - Python tests which connect to a single server and use the DynamoDB API unit, boost, raft - unit tests in C++ cqlpy - Python tests which connect to a single server and use CQL topology* - tests that set up clusters and add/remove nodes cql - approval tests that use CQL and pre-recorded output rest_api - tests for Scylla REST API Port 9000 scylla-gdb - tests for scylla-gdb.py helper script nodetool - tests for C++ implementation of nodetool

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).

To add a new folder, create a new directory, and then copy & edit its suite.ini.
