URL: https://github.com/apache/datafusion/issues/17496

   ### Is your feature request related to a problem or challenge?
   
   This is a paper cut I encountered
   
   SQL has the ability to create a table even if it already exists using the 
`OR REPLACE` syntax. 
   
   DataFusion does this today for normal tables
   ```sql
   > create table bar(x int);
   0 row(s) fetched.
   Elapsed 0.009 seconds.
   
   > create or replace table bar(z int);
   0 row(s) fetched.
   Elapsed 0.004 seconds.
   ```
   
   However, it doesn't support the same syntax for `EXTERNAL` tables:
   
   ```sql
   > create or replace external table foo(x varchar, y int) stored as parquet 
location '/tmp/foo/';
   This feature is not implemented: External tables not supported
   ```
   
   ### Describe the solution you'd like
   
   I would like the syntax above to work
   
   ### Describe alternatives you've considered

   ### Additional context
