Disable stringify_facts in puppet

[Bartłomiej Piotrowski]

By default Puppet enables stringify_facts. It can lead to weird behavior, assuming a fact, that supposedly returns an array. E.g.:

Facter: ["/", "/boot", "/var", "/var/log"]
As exposed in Puppet: "[\"/\", \"/boot\", \"/var\", \"/var/log\"]"

stringify_fact is already disabled in Puppet 4, so it makes sense to do it now to save us from possible problems in the future.

Additionally the configuration of puppet has to be updated on gate w/ fuel-library-puppet-units and on fuel-ci hosts w/ fuellib-noop tests as well.

    Disable stringify_facts on managed nodes

    By default Puppet enables stringify_facts. It can lead to weird behavior,
    assuming a fact, that supposedly returns an array. E.g.:

    Facter: ["/", "/boot", "/var", "/var/log"]
    As exposed in Puppet: "[\"/\", \"/boot\", \"/var\", \"/var/log\"]"

    It is already disabled in Puppet 4, so it makes sense to do it now to save
    us from possible problems in the future.
