Name already in use

(Copied from demo/grouper tests.)

(To avoid error messages during first start.)

These changes were not tested yet.

Configuration flex auth

User banderson is used in the shibboleth authentication demo. For that,
he needs to have a role in midPoint to be able to access the midPoint
GUI. Superuser role was chosen because the shibboleth authentication
replaces the internal authentication with default administrator account.

This requires midPoint 4.1-M2 that has been uploaded today.
Also fixing the name of user recomputation task.

…_container

Tests for REST reconciliation were added. Some obsolete tests were removed.

At least where it's possible. E.g. tier/rabbitmq currently has no tags.
tier/mariadb has only very generic tags.

…_container

This version contains (hopefully) final structure for configuration
parameters.

Also removed obsolete midpoint-objects directory in demo/grouper.

Beware! This is an incompatible change. The new connector has no support
for "old" object classes (AccountObjectClass, GroupObjectClass) and uses
a different name for "plain" groups (ri:CustomPlainGroupObjectClass ->
ri:Group). Also the name and uid attribute names has been changed to
ri:name and ri:uuid.

Obsolete midpoint-objects directory was renamed appropriately before
it's definitely deleted.

But the demo does not work (still).

This is necessary for correct state reporting.

This applies to the master branch only.

…eeded anymore now.

Although the tests are quite advanced, they are not really complete yet.
Most notably, group membership update in LDAP is not checked now.
We should include running Trigger Scanner in these tests eventually.

The "supergroup" is now obsolete and was removed. It temporarily stays
as a parameter for Grouper connector but we can specify any existing
group there, as it is used solely for the "test resource" operation.

1) add forgotten initialize.gsh file
2) fix Dockerfile FROM dependency

This is basically a clone of demo/complex2s from the laboratory branch.

Main differences:

1. Fixed "unknown host directory" error message when building
grouper_data container. The initialization script is no longer run
at build time in grouper_data. It is instead run at first start of
grouper_daemon container, when LDAP server is already up.

2. banderson and sysadmingroup is now created when building LDAP container.
So the Grouper resource test action can be executed directly, without
the need to prepare midPoint objects for banderson & sysadmingroup first.

Note that tests were not updated yet.
