Can't specify LXD project name while adding new LXD host

[vishvikkrishnan]

While adding new LXD VM host to MAAS. there is no option to specify the LXD project for the added host. MAAS automatically adds the host to the default project. The MAAS CLI takes in the optional project parameter for LXD hosts, so this option needs to be accessible within the maas_vm_host resource type.

Example configuration:

resource "maas_vm_host" "lxd_host_with_project" {
  type = "lxd"
  power_address = "10.113.1.24:8443"
  project = "MAAS" #LXD project owned by MAAS
}
