Add keycloak data to import for keycloak deployment when creating dev setup using make deploy_dev

[bazko1]

Overview

make deploy_dev Deploys breakglass, mailhog and keycloak to default cluster for ease of manual testing and evaluating.

The minor annoyance is that the keycloak is clean without client for open-id auth redirection and user with first/surname set and most importantly the email is not set which is user unique identity now.

The ui-client realm and users for testing could be defined as json and imported using some volume or side container with script.

Steps that are currently required:

Open id auth client realm

1. Login as admin and go to Clients tab and click Create:
   
2. Create client called breakglass-ui (or the same as defined in config frontend.oidcClientID) and Save

3. Set Valid Redirect URIs and Web Origins to * (or your custom ips/hostnames if prefered)

Users configuration

I usually create user test with password test and email tester@mail.com and I have escalation for such email in config/samples/
Also I add email admin@mail.com for user Admin and sample escalation has such email as approver.
