`func host start` (non-verbose) doesn't show restart logs

To repro,
1. `func host start`
2. Modify a file, say `host.json`

A restart is triggered and functions are reloaded, but you can't tell from the output of the core tools as it doesn't change. Workaround is to use `--verbose` flag.

I think that we should consider having some way of indicating that a Host restart happened.

Start by reproducing the behavior with `func host start`, editing `host.json`, and comparing normal output with `--verbose`. Trace the host restart and function reload output paths; done means a non-verbose restart is visibly indicated without relying on the verbose flag.
