If a user tries to do a re-install in a Gitea database, they gets a warning and double check.
When Gitea runs, it never create empty app.ini automatically.

Also some small (related) refactoring:

* Refactor db.InitEngine related logic make it more clean (especially for the install code)
* Move some i18n strings out from setting.go to make the setting.go can be easily maintained.
* Show errors in CLI code if an incorrect app.ini is used.
* APP_DATA_PATH is created when installing, and checked when starting (no empty directory is created any more).

* Move migrtions into services and base into modules/migration

* Fix imports

* Fix lint

* Fix bug on admin subcommand

* Add signals for all initDB

Often when handling problems it is not clear which configuration file Gitea is
using. This PR simply ensures that the configuration file is emitted.

One of the repeatedly reported issues has been that gitea produces too much console
logging during set up even if the console logger is turned off.

Fundamentally this is due to some otherwise very helpful logging that has to occur
before logging is set up. This has come to a head with the merging of #16243 where
otherwise potentially helpful Trace logging in the git module now appears on the
console.

This PR proposes three things:

1. Change the initial default logger to Info not Trace.
2. Change the logging for the AppPath things to Info in recompense.
3. Add two new command line options to gitea web: --quiet and --verbose

`gitea web -q` or `gitea web --quiet` will only log Fatal level initially.
`gitea web -verbose` will log at Trace.
