[bug] Invalid value for input variable 'authentication'

[viniciusdc]

Describe the bug

0.4.0 test tracker: #976

During deployment, qhub 0.4.0.dev64+g25b2eaa on local minikube and aws, me and @iameskild noticed the following error during deployment when using Auth0/Github based auth:

INFO:qhub.provider.terraform:terraform apply directory=stages/06-kubernetes-keycloak-configuration targets=[]
INFO:qhub.provider.terraform: terraform at /tmp/terraform/1.0.5/terraform
[terraform]: ╷
[terraform]: │ Error: Invalid value for input variable
[terraform]: │ 
[terraform]: │   on /tmp/tmp_hmra46m.tfvars.json line 1:
[terraform]: │    1: {"realm": "qhub-thisisatest", "authentication": {"type": "Auth0", "config": {"client_id": "***************************", "client_secret": "***************************", "auth0_subdomain": "***************************"}}}
[terraform]: │ 
[terraform]: │ The given value is not valid for variable "authentication": all map
[terraform]: │ elements must have the same type.
[terraform]: ╵

the above issue is due to the fact that terraform expects a map of one type variable for authentication which is not the case, as its receiving from input a string and map as its values, see for reference this issue/comment.

The following change will fix the above issue:

variable "authentication" {
  description = "Authentication configuration for keycloak"
  type = object({
    type = string
    config = map(string)
  })
}

edit. Due to some restrictions created with the usage of object as type, another more general option type = any is more advantageous.

Expected behavior

• authentication variable should be correctly loaded into terraform
