This patch does refactoring necessary to support execution of DDL commands on remote servers. Basically it extends cross module api with ddl_command_start, ddl_command_end and sql_drop functions. Variable hypertables_list added to ProcessUtilityArg. It is used to keep a list of found hypertables during Utility/DDL statement parsing. This information and information gathered from other hook functions will be used to distinct distributed hypertables and forward DDL commands to any remote servers associated with them.
