* chore: add health check endpoint

docs: update document about health check

fix: fix up Sqlite3 ping. current ping will success even if the db file is missing

fix: do not expose privacy information in output field

* refactor: remove HealthChecker struct

* Added `/api/healthz` to install routes.

This was needed for using /api/healthz endpoint in Docker healthchecks,
otherwise, Docker would never become healthy if using healthz endpoint
and users would not be able to complete the installation of Gitea.

* Update modules/cache/cache.go

* fine tune

* Remove unnecessary test code. Now there are 2 routes for installation (and maybe more in future)

* Make docker gitea/gitea:v1.16-dev etc refer to the latest build on that branch

One of the problems with our current docker tagging is that although we
have strict version tags, latest and dev we do not have a way for docker
users to track the current release branch. This PR simply suggests that
we use the 1.x-dev tag for these and we build and push these. This will
give users who want or need unreleased bug fixes the option of tracking
the pre-release version instead of simply jumping to dev.

* Database preparation: Clarify why database client is installed on Gitea server

The database client program (`mysql` or `psql`) is used to test database
connection, but Gitea use Go's database driver to do the same.

Also, rename "server part" and "client part" to "server application" and
"client program" to disambiguate.

I think it's a bad default to have "dev" as the default run mode which
enables debugging and now also disables HTTP caching. It's better to
just default to a value suitable for general deployments.
