1.9 doesn't set the dns-search option in the generate /etc/network/interfaces

[Blake Rouse]

When a node is deployed in MAAS 1.9 and curtin generates the /etc/network/interfaces it does not include the dns-search path. So anytime a user does:

sudo they see:
sudo: unable to resolve host maas1

To fix this issue both MAAS and curtin need to be fixed.

1. MAAS needs to provide a list of dns-search paths for curtin.
2. Curtin needs to place that information in the generated /etc/network/interfaces.

Attached branch has a fix. dns-search can be appended in two places:

- subnets
  - type static
    address 1.1.1.1
    dns-search:
       - path1
       - path2

or

- subnets
  - type static
    address 1.1.1.1
    dns-search: path1 path2

or

- nameserver
  address: 8.8.8.8
  search: path1 path2

or

- nameserver
  address: 8.8.8.8
  search:
    - path1
    - path2

curtin will inject

dns-search <paths> either under the specified interface (if configured under subnets)
or if using nameserver config, then it will appear underneath all iface lines.

Fix has landed in trunk.

This bug is believed to be fixed in curtin in 17.1. If this is still a problem for you, please make a comment and set the state back to New

Thank you.
