[feat-4496][server] Add to! {} is used to mark the custom parameters to be output as-is in sql (#4497) 

* feat([server]): Add to! {} is used to mark the custom parameters to be output as-is in sql

Before pre-compiling sql, replace the custom parameters marked with !{}
to prevent the parameters in the hive plus partition path from being
replaced with single quotes

Closes This closes #4496
