Updated tests, API, and account manager methods
Sync routes to peers in the distribution groups
Added store upgrade by adding the All group to routes that don't have them
This PR brings user invites logic to the Management service
via HTTP API.
The POST /users/ API endpoint creates a new user in the Idp
and then in the local storage.
Once the invited user signs ups, the account invitation is redeemed.
There are a few limitations.
This works only with an enabled IdP manager.
Users that already have a registered account can't be invited.
