Bug description:
  Currently DHCP appears to be an all or nothing boolean, which is
  insufficient for many network configurations.

  Ideally all of the DHCP configuration options supported by systemd would also be supported in netplan:
  https://www.freedesktop.org/software/systemd/man/systemd.network.html#%5BDHCP%5D%20Section%20Options


  As an example, consider the following netplan configuration:

  network:
    version: 2
    renderer: networkd
    ethernets:
      enp0s3:
        dhcp4: yes
        nameservers: [8.8.8.8,8.8.4.4]

  
  After running netplan apply I check the nameservers with systemd-resolve --status and it shows:

  DNS Servers: 8.8.8.8
               8.8.4.4
               192.168.1.1

  Here, "192.168.1.1" was provided by my DHCP server.  On this
  particular node, I only want the manually configured DNS servers, but
  netplan has no way to indicate this.
