Initial admin user (1) should be creatable without password

[gganssauge]

In my test portal I created a user in the admin group with kickstarter and removed the default admin user (id #1) from the admin group to mitigate the risk of a well-known admin user.
That had the unfortunate consequence that the portal-kong-adapter, portal-mailer and portal-chatbot containers did no longer start.
To mitigiate that risk anyway it would be useful to create the admin user without a passwort from the start - iff another admin user was configured.

This will be fixed in two ways:

• It will be possible to remove the Admin User altogether
• Each webhook/plugin service will be able to use the wicked-sdk to create its own Admin machine user
• This makes it visible which webhook/service calls the API, and not only shows userId: 1

[DonMartin76]

This has been partly fixed: All services (kong adapter, mailer, chatbot) now - as of 0.10.0 use a service user to connect to the API, but it is still not possible to remove the '1' user altogether just yet.

Parts will surface in 0.10.0, but it's still not possible to remove the 1 user yet.

But it will be possible to define users

a) Without password
b) with a predefined customId

This makes it possible to e.g. predefine GitHub users ("customId": "Github:<id>") which without any additional configuration are administrators on the portal. Very neat.

It is since long possible to create users with a given custom ID, e.g. the Google-ID.

The most common use cases are possible by now. Closing this.
