<!-- Describe what has changed in this PR --> **What changed?** Moved `temporalite` and `temporaltest` packages from Temporalite. This is an alternate version of https://github.com/temporalio/temporal/pull/4006. <!-- Tell your future self why have you made these changes --> **Why?** Step 1 in the plan to deprecate the Temporalite repository: https://github.com/temporalio/temporalite/issues/202 <!-- How have you verified this change? Tested locally? Added a unit test? Checked in staging env? --> **How did you test it?** `go test ./temporaltest` <!-- Assuming the worst case, what can be broken when deploying this change to production? --> **Potential risks** A non-semver-breaking backwards compatibility guarantee is being included in the new packages which we would need to abide by. For now only the `temporaltest` package is public, so we are free to perform additional refactoring on `temporalite` and potentially consolidate it into a simple set of `temporal.ServerOption` functions. <!-- Is this PR a hotfix candidate or require that a notification be sent to the broader community? (Yes/No) --> **Is hotfix candidate?** No --------- Co-authored-by: Yimin Chen <[email protected]>
