    Puppet hieradata does not properly interpret an IPv4-mapped IPv6

    IPv6 IPv4-mapped prefix ::ffff is being interpreted by puppet as
    a Hiera parameter reference, causing a Hiera parameter lookup
    error. "puppet lookup platform::dns::resolv::servers" shows error
    when the value in yaml file leads with ::. This commit fixes the
    issue by putting the value in quote on yaml dump.

    TEST PLAN:
        PASS: Bootstrap with dns_servers ::ffff:10.10.10.1
        PASS: system dns-modify nameservers=::ffff:10.10.10.1
