Gitpod ports await look also is the service available

Is your feature request related to a problem? Please describe

When you start a MySQL server in Docker and you want to execute a MySQL command directly it's annoying as you have to wait for the right moment where the server is available

With gp ports await 3306 you get notified when the port is reachable. But port reachable is not the same as useable. You get then weird errors like `MySQL server has gone away'.

Describe the behaviour you'd like

Add an --type mysql to the command to try to connect to the MySQL server instead of just looking is the port open

Describe alternatives you've considered

until mysqladmin ping; do
          sleep 1
done

Works but for DX it would be better I guess when it would be easier to do that

Additional context

I would like to implement that also
