feat(python): add namespace/table exist support (#3460)

Browse Source

In the current LanceDB usage implementation, there is no way to check
whether a table or namespace already exists. This PR introduces the
namespace_exists and table_exists methods to determine the existence of
tables and namespaces.

useage like this:
```
# check table exists
db.table_exists(table_id=['xxx'])

# check namespace exists
db.namespace_exists(namespace_id=['xxx'])
```

fixes: #3419
