feat: allow creation of roles

[rwlodarczyk-xealth]

Feature Request

Describe the Feature Request
Currently there is no way to create roles in Lacework via Terraform. It seems like users can be assigned to roles, but the roles need to be created in the UI first.

Is your feature request related to a problem? Please describe
We'd like to get all of our configuration for Lacework into Terraform so that we can track changes via git.

Describe Preferred Solution
Create:

resource "lacework_role" "read_only" {
  name = "Read only Role"

  alerts = ["READ"] # valid values: ["READ"], ["WRITE"], ["DELETE"], ["READ", "WRITE"], ["READ", "WRITE", "DELETE"]
  compliance = ["READ"]
  vulnerabilities = ["READ"]
  code_security = ["READ"]
  resources = ["READ"]
  policies = ["READ"]
  reports = ["READ"]
  subscription = ["READ"]
  identities = ["READ"]
  attack_path = ["READ"]

  notifications {
      channels = ["READ"]
      rules = ["READ"]
  }

  integrations {
      accounts = ["READ"]
      identity_providers = ["READ"]
      container_registries = ["READ"]
  }

  configuration {
      resource_groups = ["READ"]
      api_keys = ["READ"]
      agents = ["READ"]
      report_rules = ["READ"]
      data_export = ["READ"]
      ai_assistants = ["READ"]
      general = ["READ"]
  }

  usage {
      license = ["READ"]
      audit_logs = ["READ"]
      authentication = ["READ"]
  }

  access_control = ["READ"]
}

resource "lacework_team_member" "severus" {
  provider   = lacework.org
  first_name = "Severus"
  last_name  = "Snape"
  email      = "severus@hogwarts.io"
  role       = "Read only Role"
}
