Ps 1904 (#2439)

* Add self host notification launch settings

* Exclude current context from push for password updates

This is needed to allow the current context to process a key
rotation if one is being done.

Does not change any other call to `PushLogOut`.

* Revert inverted exclude logic

This exclude is referring to exempting the requesting client
from the notification push.
