Re-fresh Session/Connection

[danvergara]

Is your feature request related to a problem? Please describe.

It's odd to see that when a database container is shutting down, dblab doesn't do anything about it. The expected behavior: when that happen, dblab should return an error message.

Describe the solution you'd like

It would be nice if dblab let you know that the session/connection has expired and then display some sort of form to get the new values for a new database connection (just like pgweb does).

Describe alternatives you've considered

Another options is just stop the execution and show an error message on the std output.
