Change some resource arguments to required and add autodoc documentation

[howto-kubernetes-info]

Foreman requires mtu, network type, ipam and boot mode but they was flagged as optional in this module. Changed arguments to required and added autodoc documentation.

cat main.tf

terraform {
  required_providers {
    foreman = {
      source  = "terraform-coop/foreman"
      version = "0.6.2"
    }
  }
}

provider "foreman" {
  provider_loglevel = "DEBUG"
  provider_logfile = "terraform-provider-foreman.log"

  client_username = <hidden>
  client_password = <hidden>
  client_tls_insecure = "true"
  location_id = -1
  organization_id = -1

  server_hostname = "192.168.122.244"
  server_protocol = "https"
}

resource "foreman_subnet" "example" {
  mask = "255.255.255.0"
  name = "10.228.247.0 BO1"
  network = "10.228.247.0"
  #network_type = "IPv4"
  #boot_mode = "DHCP"
  #ipam = "DHCP"
  #mtu = 1500
}

Terraform apply output :

terraform apply

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following
symbols:
  + create

Terraform will perform the following actions:

  # foreman_subnet.example will be created
  + resource "foreman_subnet" "example" {
      + __meta__ = (known after apply)
      + id       = (known after apply)
      + mask     = "255.255.255.0"
      + name     = "10.228.247.0 BO1"
      + network  = "10.228.247.0"
    }

Plan: 1 to add, 0 to change, 0 to destroy.

Could you run the autodoc command to update the docs accordingly?

@bitkeks I updated the docs accordingly. Should be fine to merge
