Revert "Merge pull request #3090 from adrienthebo/issue/master/pup-1106-check-for-failed-deps-on-refresh"

This broke the acceptance test tests.ticket_7728_don't_log_whits_on_failure.rb,
so I'm backing it out until I can update the whit acceptance test as
well.

This reverts commit ec03dee5ac403d0c110cb8c65103c0f4a2ee8391, reversing
changes made to 7b410fe1c94f37a8ad5732affb7e2d9355b38289.
(maint) Add Equifax cert for pmt acceptance

The forge SSL certificates are being updated to use SHA-256, and that's
introduced a new certificate dependency that's not present on Windows.
Add it as part of acceptance testing. This is a stop-gap until the PMT
is fixed to come with its own certs.

(PUP-1019) Remove ZAML

Before this commit we were using ZAML by monkey patching the `to_yaml`
function to use ZAML.dump instead of YAML.dump. After removing `zaml.rb`
tests started failing because of the way that ZAML serialized YAML so
assertions in those tests were changed.

This commit also adds in a patch to YAML.Psych to handle the cases where
ruby objects were being encoded improperly.

This commit removes the use of ZAML in puppet as part of the Puppet 4.x
code removal efforts.

(PUP-1019) Fix serializing environments.

This commit fixes a regression with Puppet::Node::Environment
serialization. When a Puppet::Node::Environment object would be
serialized the entire object was serialized instead of just the
environments name.

(PUP-3682) Disable HTTP keepalive in webrick on 1.8.7

Previously, webrick would attempt to support HTTP keepalive so that HTTP
clients could send multiple HTTP messages on the same TCP (SSL)
connection. However, we found in practice that RHEL6 with system ruby
1.8.7-p352 with openssl 1.0.1e-fips does not reliably handle keepalive.
Most commonly the webrick server fails to read the agent's report, or
sometimes fails when handling the agent's catalog request:

    Server Error: SSL_read:: internal error

This commit causes the webrick rest handler to always include the HTTP
header `Connection: close` in the HTTP response. This indicates to the
HTTP client that the webrick server does not want to keep the connection
alive, and that the client should make a new connection the next time it
connects.

This change does not affect webrick running under 1.9 or later, nor does
it affect puppet masters running under passenger or puppet-server. As
these do reliably handle HTTP keepalive, and we want the performance
benefit that persistent http connections provide.

Note 1.8.7 support will be going away in Puppet 4, so this is a
short-term fix to the 3.7.x series.
