This commit adds support for executing ALTER KS for keyspaces with tablets and utilizes all the previous commits. The ALTER KS is handled in alter_keyspace_statement, where a global topology request in generated with data attached to system.topology table. Then, once topology state machine is ready, it starts to handle this global topology event, which results in producing mutations required to change the schema of the keyspace, delete the system.topology's global req, produce tablets mutations and additional mutations for a table tracking the lifetime of the whole req. Tracking the lifetime is necessary to not return the control to the user too early, so the query processor only returns the response while the mutations are sent.
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/

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.
