Description

It will be helpful to have a session option, something like ENABLE_AUTO_TESTCASE_COLLECTION, which the users can set in a session and the test cases for all the QueryStmts running in that session are captured in a directory. This way, users don't need run "create testcase" for each query individually. Should be turned off by default.

Since this potentially increases the planning time, a warning in the runtime profile would be helpful for debugging.
