Fix applying query masking rules to ddl statements.

[MikhailBurdukov]

Changelog category (leave one):

• Bug Fix (user-visible misbehavior in an official stable release)

Changelog entry (a user-readable short description of the changes that goes into CHANGELOG.md):

Prevent query masking rules from being incorrectly applied to DDL statements.

Documentation entry for user-facing changes

• Documentation is written (mandatory for new features)

Details

If query masking rules are specified, then it will be applied to DDL queries and replaced valid statement with masking. Such behaviour causes that the node in zk with DDL task will have already formatted query.
