feat(types): Deprecate the DBBackend variable in favor of new app-db-backend config entry (#11188) * [10948]: Add changelog entry. * [10948]: Deprecate the types.DBBackend variable and the NewLevelDB function. Create a NewDB function to replace them. * [10948]: Add a DBBackend string to the simulation config and a flag for setting it. Update the simulation setup to use that instead of the compile-time DBBackend variable. * [10948]: Update the mock app creator to use the NewDB function. Not sure what to do about the db backend in that case though. * [10948]: Update changelog to reflect new db-backend field name. * [10948]: Use the tendermint db-backend type for the snapshot db. * [10948]: Update the last use of NewLevelDB by adding a parameter to openDB and uppdating calls to that to provide the db type to use. * [10948]: Upddate the NewDB function to also have a default db backend type if an empty string is provided there. * [10948]: Remove the new TODO in mock.NewApp. After looking through it's uses, there doesn't seem to be any desire to change it, and there's no easy way to communicate it. * [10948]: Enhance the NewDB defer function to also add info to any err that is being returned. * [10948]: Add some unit tests for NewDB. * [10948]: Lint fixes. * [10948]: Add a changelog entry to the deprecated section. * [10948]: Update the makefile to no longer set the types.DBBackend value. * [10948]: Use memdb for the mock app instead of goleveldb. I know it was a goleveldb before, but for a mock app, a memdb feels like a better choice (assuming 'mock' and 'mem' mean what I assume they mean). * [10948]: Fix the store benchmark tests (had some index-out-of-range issues). * [10948]: Fix cachekv store bench test calling iter.Key() before checking iter.Valid(). * [10948]: Remove the panic recovery from types.NewDB since dbm.NewDB returns an error now (it didn't originally, when NewLevelDB was first written). * [10948]: Add changlog entry indicationg an API breaking change due to the DBBackend change. * [10948]: Get rid of the types.NewDB function in favor of just using the tm-db version of it. * [10948]: Fix Update the codeql-analysis github action to use go v1.17. * [10948]: Add config file option for the app db backend type. * [10948]: Adjust the comment on the app-db-backend config entry to clarify fallback behavior. * [10948]: Add a default of GoLevelDBBackend to GetAppDBBackend. The old DBBackend variable defaulted to that, and some unit tests assume that behavior still exists. * [10948]: Add the missing quotes around the app-db-backend value. * [10948]: Small tweak to the changelog's deprecated entry. * Add the go version declaration back into the codeql-analysis github action. * [10948]: Update new use of openDB. * [10948]: Put a brief delay after closing the test network. Hopefully that helps with address-in-use and non-empty directory errors. Co-authored-by: Marko <marbar3778@yahoo.com>
