This series add a new config option: `tablets_mode_for_new_keyspaces` that replaces the existing
`enable_tablets` option. It can be set to the following values:
disabled: New keyspaces use vnodes by default, unless enabled by the tablets={'enabled':true} option
enabled: New keyspaces use tablets by default, unless disabled by the tablets={'disabled':true} option
enforced: New keyspaces must use tablets. Tablets cannot be disabled using the CREATE KEYSPACE option
`tablets_mode_for_new_keyspaces=disabled` or `tablets_mode_for_new_keyspaces=enabled` control whether
tablets are disabled or enabled by default for new keyspaces, respectively.
In either cases, tablets can be opted-in or out using the `tablets={'enabled':...}`
keyspace option, when the keyspace is created.
`tablets_mode_for_new_keyspaces=enforced` enables tablets by default for new keyspaces,
like `tablets_mode_for_new_keyspaces=enabled`.
However, it does not allow to opt-out when creating
new keyspaces by setting `tablets = {'enabled': false}`

* github.com:scylladb/scylladb:
boost/tablets_test: verify failure to create keyspace with tablets and non network replication strategy
tablets: enforce tablets using tablets_mode_for_new_keyspaces=enforced config option
db/config: add tablets_mode_for_new_keyspaces option
The new option deprecates the existing `enable_tablets` option.
It will be extended in the next patch with a 3rd value: "enforced"
while will enable tablets by default for new keyspace but
without the posibility to opt out using the `tablets = {'enabled':
false}` keyspace schema option.

This patch makes it clear which Raft recovery procedure is used in
each test.
Tests with "This test uses the gossip-based recovery procedure." are
the tests that use the gossip-based topology. This tests should be
deleted once we make the Raft-based topology mandatory.
Tests with the new FIXME are the tests that use the Raft-based
topology. They should be changed to use the Raft-based recovery
procedure or removed if they don't test anything important with
the new procedure.
