Title:
  broken generation of  wpa config for hashed passwords

Status in netplan:
  Fix Released
Status in netplan.io package in Ubuntu:
  Fix Released

Bug description:
  Have a look at the netplan.io config file at
  https://gist.github.com/fluffy/e2a202a0816299d519dabf7bbed2f7bb for
  802.1 auth for a wired network.

  This will generate a wpa config file at /run/netplan/wpa-enp4s0.conf
  that has

  password="hash:83d…0b11"

  However, this is not correct. It should not have the quotes and should
  look like

  password=hash:83d…0b11

  The quotes cause the wpa_suppicant to not detect this is a hashed
  password and instead think it is a normal password that starts with
  hash:

  This is an important bug because at Cisco we can not store our
  passwords unhashed on disk and our production network requires 802.1x
  auth. I think this is simple to fix and I'm glad to send a PR or any
  other information that helps fix it.

  Thank you for looking at this, Cullen
