Implement mypy in the most non-breaking way possible. There's still some
changes of behavior that crept in, merely due to incorrect edge case
handling.
Charm libraries are generally well typed, include py.typed marker for
all of the libraries, to allow mypy analyzing their usage.

Previously on application remove,
tempest-k8s charm would error at the relation-broken hook,
causing the removal to fail:
```
tempest/0* error idle 10.1.169.40 hook failed: "identity-ops-relation-broken"
```
with traceback:
```

self.charm.set_tempest_ready(False)

```
This fixes the issue for tempest (and potentially if similar issues
are present on other sunbeam charms),
by checking if peels_rel exists because trying to interact with it.

Currently `get_all_unit_values` will return the values set by
remote units. The new `include_local_unit` option will add the
value that the local unit has set to the list.

If a remote unit has not provided a value for a given key don't
append to the values list - this results in Python None being
added to the list which causes issues in consuming templates
and code.
