Dataset for organizations

[pedroigor]

Closes #856

[pedroigor]

@martin-kanis @vmuzikar @sguilhen Please, let me know if you want to add more operations/settings when provisioning organizations.

I tried to start with the bare minimum to start working on the scalability of groups and identity providers. For the latter, it is already possible to see how much identity providers degrade performance when rendering login pages.

[martin-kanis]

@pedroigor Thanks, overall looks good to me. Please see my comments regarding usability.

[martin-kanis]

Parameter count is required here but it doesn't make sense, as I want to create just one org and if I provide count=5 it is ignored.

[pedroigor]

Yeah, it is a limitation. Otherwise, I'll need to create add another parameter just to make it optional.

[martin-kanis]

This crashes my Keycloak instance, consider lowering number of users or number of orgs in the example.

[pedroigor]

I can create even more orgs than 1k. Do you have more details what it is failing for you?

@pedroigor With the latest version and Keycloak 25, I'm getting

Am I doing something wrong?
