To enable tablets replication one needs to turn on the (experimental) feature and specify the `initial_tablets: N` option when creating a keyspace. We want tablets to become default in the future and allow users to explicitly opt it out if they want to.
This PR solves this by changing the CREATE KEYSPACE syntax wrt tablets options. Now there's a new TABLETS options map and the usage is
* `CREATE KEYSPACE ...` will turn tablets on or off based on cluster feature being enabled/disabled
* `CREATE KEYSPACE ... WITH TABLETS = { 'enabled': false }` will turn tablets off regardless of what
* `CREATE KEYSPACE ... WITH TABLETS = { 'enabled': true }` will try to enable tablets with default configuration
* `CREATE KEYSPACE ... WITH TABLETS = { 'initial': <int> }` is now the replacement for `REPLICATION = { ... 'initial_tablets': <int> }` thing

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.
