Show more user-friendly output, from the `start` command

### Description

Currently, the `limactl start` defaults to dumping the log with the INFO level to the console.

Turning off the logging means that only the final message (if any), was showing to the user.

I was experimenting with a less verbose mode, that only showed the major progress steps...

There were only two events in the start, Booting and Running, so I wanted to add requirements.

Booting: `INFO[0000] SSH Local Port: 60022 `

* `Starting "default"`

Running: `INFO[0028] READY. Run `lima` to open the shell. `

* `READY.`

The log also has some internal info, like mounts and forwards.

```
INFO[0000] [hostagent] Waiting for the essential requirement 1 of 5: "ssh"
INFO[0010] [hostagent] Waiting for the essential requirement 1 of 5: "ssh"
INFO[0017] [hostagent] The essential requirement 1 of 5 is satisfied
INFO[0017] [hostagent] Waiting for the essential requirement 2 of 5: "user session is ready for ssh"

INFO[0028] [hostagent] Waiting for the final requirement 1 of 1: "boot scripts must have finished"
INFO[0028] [hostagent] The final requirement 1 of 1 is satisfied
```

Counted the total, and added a progress bar:

```console
$ limactl --silent start --progress
Starting "default"
Waiting 1 / 8 [--->________________________] "ssh" (essential 1/5)
Waiting 2 / 8 [------>_____________________] "user session is ready for ssh" (essential 2/5)
Waiting 3 / 8 [---------->_________________] "sshfs binary to be installed" (essential 3/5)
Waiting 4 / 8 [------------->______________] "fuse to \"allow_other\" as user" (essential 4/5)
Waiting 5 / 8 [----------------->__________] "the guest agent to be running" (essential 5/5)
Waiting 6 / 8 [-------------------->_______] "systemd must be available" (optional 1/2)
Waiting 7 / 8 [------------------------>___] "containerd binaries to be installed" (optional 2/2)
Waiting 8 / 8 [----------------------------] "boot scripts must have finished" (final 1/1)
READY.
```

Found it less distracting, if the old steps remained.

By default, the new step information replaces the old.
