Determine which timeout we need to apply at prepare time. We
don't know the numerical value (since it depends on whoever is
executing the query, not just the statement type), but we know
which member of timeout_config we need, so determine and remember
that.
The storage_proxy represents the entire cluster, so there's never a need
to access it on a remote shard; the local shard instance will contact
remote shard or remote nodes as needed.
Simplify the API by passing storage_proxy references instead of
seastar::sharded<storage_proxy> references. query_processor and
other callers are adjusted to call seastar::sharded::local() first.

When a table, keyspace, or role is created, the creator now is
automatically granted all applicable permissions on the object.
This behavior is consistent with Apache Cassandra.
Fixes#3216.
This changes announce_migration() to return a change event directory in
schema_altering_statement base class. It's needed for drop index
statement, which does not know the keyspace or column family until it
looks up them based on the index. Two stage approach of announcing a
migration and then creating the change event won't work because in the
latter stage, the lookup will fail. The same change in
announce_migration() has been applied to Apache Cassandra.
In preparation for splitting raw and prepared variants of subclasses
of schema_altering_statement, remove schema_altering_statment::prepare().
All subclasses already implement it themselves (by creating a new instance).
Pass a reference to storage_proxy and apply mutations in
legacy_schema_tables::merge_schema().

There's a cyclic dependency between cql3 and transport namespaces when
we introduce prepared statements. The latter pulls
parsed_statement::prepared from the former. Break the cycle by using
a forward delcaration in cql_statement.hh.
