Gorm [Feature Request] Support UNIX Socks

Describe the feature

Unix Sock support, such as /var/run/mysqld/mysqld.sock.

Motivation

Support would enable a shared sock to be provided (such as for multiple Dockers) to communicate to a DB server without the need of maintaining networks.

Related Issues

None.

Nevermind, this is entirely possible because it uses the Go backend that already has this feature. It's not documented in Gorm. @unix(/full/path/to/db_server.sock) works. Maybe update the documentation? Will leave open for your decision to document.
