Use non_zero_wait to override modulo 0

Push the unit % modulo == 0 logic to modulo_distribution. In
distributed_wait check for leadership and return 0 if the leader
or call modulo_distribution with non_zero_wait=True.

Non-leader should be modulo * wait

Per requests changing non-leader to get modulo * wait rather than
(modulo + 1) * wait.

Handle non-zero unit numbered leader

When the distributed_wait function is called and the leader does not
happen to have 0 unit number, the leader winds up waiting while the
non-leader modulo 0 does not. Also when there are units > modulo
there may be conflicts with the leader when multiple units get modulo
0 and do not wait. Neither of these are desired behavior.

This change makes sure the leader, regardless of modulo, never waits.
And forces non-leaders which happen to get modulo 0 to wait.

For applications where the original behavior is desirable,
modulo_distribution can be used directly.

Fix network get (#118)

* Add egress_subnets helper to access egress-subnets on a relation

* Fix NotImplemented fallbacks for network information APIs
