bug: proxy scanner config.yml converts bool to string

[credibleforce]

Describe the bug
When using the kubernetes admission controller module a config.yml secret is created based on inputs. The inputs include bool values get converted to strings during deployment. As a result the proxy-scanner deployment fails to start complaining about casting string value as bool.

Module setup:

module "lacework_admission_controller" {
  source  = "lacework/admission-controller/kubernetes"
  version = "~> 0.1"

  lacework_account_name = "${var.lacework_account_name}"
  proxy_scanner_token   = "${var.proxy_token}"
  default_registry      = "index.docker.io"
  static_cache_location = "/opt/lacework"
  scan_public_registries = true

  registries = [
    {
      name      = "docker_public"
      domain    = "index.docker.io"
      ssl       = true
      auto_poll = false
      is_public = true
      disable_non_os_package_scanning = false
    },
    {
      name      = "github_public"
      domain    = "ghcr.io"
      ssl       = true
      auto_poll = false
      is_public = true
      disable_non_os_package_scanning = false
      notification_type = "ghcr"
    }
  ]
}

Error message from the failing pod:

Checking the values set in the lacework-proxy-scanner secret config.yml looks like this:

"lacework":
  "account_name": "xxxxxxxx"
  "integration_access_token": "xxxxxxxxx"
"registries":
- "auto_poll": "false"
  "disable_non_os_package_scanning": "false"
  "domain": "index.docker.io"
  "is_public": "true"
  "name": "docker_public"
  "ssl": "true"
- "auto_poll": "false"
  "disable_non_os_package_scanning": "false"
  "domain": "ghcr.io"
  "is_public": "true"
  "name": "github_public"
  "notification_type": "ghcr"
  "ssl": "true"
"scan_public_registries": true
"static_cache_location": "/opt/lacework"

Pod starts if I update the config to the following:

"lacework":
  "account_name": "snifftest"
  "integration_access_token": "_cb55f1031e5a700427b2536651d42142"
"registries":
- "auto_poll": false
  "disable_non_os_package_scanning": false
  "domain": "index.docker.io"
  "is_public": true
  "name": "docker_public"
  "ssl": true
- "auto_poll": false
  "disable_non_os_package_scanning": false
  "domain": "ghcr.io"
  "is_public": true
  "name": "github_public"
  "notification_type": "ghcr"
  "ssl": true
"scan_public_registries": true
"static_cache_location": "/opt/lacework"

Expected behavior
Bool values for registries in module input should continue to be bool and not converted to string when set in the config.yml secret.
