When starting a machine and the user has not explicitly passed
-u=true|false AND stdin is a not a tty, we should not prompt to update
connections.

This allows users to set the associated machine's system connection to the system default when running `podman machine init --now` or `podman machine start`. It also changes the default bbehavior of these commands in that the user will be prompted and asked if they would like to switch the system connection. It also introduces a command line switch called `--update-connection`. If the switch is unset, then the user will be prmpted. If the command value is explicitly set to `false`, the user will not be prompted and the system connection will not be altered. If the value is set to `true`, the system connection will be made the default and the user will not be prompted.
