There's nothing legacy about it so rename legacy_schema_tables to
schema_tables. The naming comes from a Cassandra 3.x development branch
which is not relevant for us in the near future.

Remove commented out isReadyForBoostrap. We don't have a StageManager
nor we will so drop the function.

Rename "MIGRATION_DELAY_IN_MSEC" to "migration_delay" as the unit of
time is already clear from the type.

Use get_storage_proxy() and get_local_storage_proxy() helpers under the

The migration_manager and migration_task logging is currently not
visible in the logs. Fix that by de-thread-localizing both loggers.

The code does:
auto fm = make_lw_shared<std::vector<frozen_mutation>>(schema.begin(), schema.end());
return net::get_local_messaging_service().send_message_oneway(net::messaging_verb::DEFINITIONS_UPDATE,
std::move(id), std::move(fm));
ms.register_handler(net::messaging_verb::DEFINITIONS_UPDATE, [this] (std::vector<frozen_mutation> m) {
...
}
We should not send a lw_shared_ptr, but std::vector<frozen_mutation>.
However, from Gleb:
Well, this is not a bug, this is really cool (and to be honest
unintended) feature of RPC. It is smart enough to detect that it is a
smart pointer to an object and dereference it. But in this particular
case there is not justification to use shared_ptr in the first place.
So, drop the lw_shared_ptr anyway.
Announce schema mutations in a cluster via the DEFINITIONS_UPDATE verb
and pass them to merge_schema() at endpoints.

We always operate on the local storage proxy so pass it by reference.
This simplifies DEFINITIONS_UPDATE message handler where all we have is
a "this" pointer to the local storage proxy.

If keyspace already exists, throw a already_exists_exception like Origin
does. Spotted while reading the code.
