Check if a table exists

Check if table id exists.

This operation should behave exactly like DescribeTable, except it does not contain a response body.

For DirectoryNamespace implementation, a table exists if either:

• The table has Lance data versions (regular table created with CreateTable)
• A .lance-reserved file exists in the table directory (declared table created with DeclareTable)

POST /v1/table/{id}/exists
