   update:
   add a option for loading tsfile sql statement.
   Now the statement for loading tsfile looks like this:
   
   {code:sql}
   load "<path/dir>" [schema=true/false] [level=int] [metadata=true/false]
   {code}
   
   for example,
   we want to load tsfiles with auto creating schema, and storage group level is 1, and need metadata check, we can input sql:
   
   {code:sql}
   load "/Users/Desktop/data/1575028885956-101-0.tsfile" schema=true,level=1,meatadata=true
   {code}
   
   if the options is missing, the default value is "schema=true,level=1,metadata=true".
   for example, when we input sql:
   
   {code:sql}
   load "/Users/Desktop/data/1575028885956-101-0.tsfile"
   {code}
   
   means:
   
   {code:sql}
   load "/Users/Desktop/data/1575028885956-101-0.tsfile" schema=true,level=1,meatadata=true
   {code}
