This also includes a number of significant changes to the SQLite state made possible by removal of the legacy DB. 1. Enable database unit tests for SQLite state, with numerous tweaks to get tests passing. Most notable changes are to container removal - where we previously didn't return an error if there was no container to remove - and RemovePodContainers, which I don't think ever worked properly from my reading of the failures. 2. Removal of AddContainerToPod/RemoveContainerToPod. On SQLite, these functions are identical to AddContainer/RemoveContainer and there is no reason to retain duplicates. 3. Removal of SafeRewriteContainerConfig - it's identical to RewriteContainerConfig in SQLite, no reason to have duplicate entrypoints. As an exciting side-note, this removes Podman's requirement that containers and pods cannot share a name, which was a BoltDB restriction only. Signed-off-by: Matt Heon <matthew.heon@pm.me>
