Fix listing app customers

Previously, only the first 25 app customers would be listed on the App details page.

Fix adding customers who are already platform users

The Control Panel would add users of connections other than 'email' to be added as customers to apps. This resulted in the user being unable to login via passwordless magic login links.

Update Helm Client

Upgrading helm client from 2.8.2 to 2.9.1

Fix access logs

Parsing of Elasticsearch credentials was raising an exception. This change passes the credentials in component form, to avoid parsing issues.

Fix customer passwordless login

The Control Panel API retrieves an Auth0 Authorization group using a webapp's name attribute, but the groups are created using the webapp slug attribute. This resulted in some apps having a second authorization group which granted no permissions to the customers added to it, meaning they could not login to the webapp.

First Concourse deployable release
