Assume modern Linux in our haproxy omnibus builds

[tas50]

We no longer support RHEL 5 or SLES 11 which were pre-Linux 2.6.28. We can now assume Linux 2.6.28 everywhere.

This looks reasonable and is quite welcome. My only hesitation with approving it is our main usage of haproxy is with chef-backend, and we don't currently have any testing around that.

We might want to try bumping this to at least 1.6.14 while we are here. As @markan says we should probably test this with chef-backend before release.

Hi @tas50 and @PrajaktaPurohit,
Done testing with chef-backend (2.0.30) and chef-server build from PR #1764. To create chef-server I was facing error There was an error parsing `Gemfile`: There are no gemspecs at /opt/opscode/embedded/lib/ruby/gems/2.6.0/gems/inspec-core-bin-4.16.0. Bundler cannot continue which was resolve with changes https://github.com/chef/chef-server/pull/1774/files.
Testing steps followed as:

1. Ran chef-server-ctl test on fe1 and fe2. Got successful result with 172 examples, 0 failures, 2 pending as https://chefio.atlassian.net/secure/attachment/35567/35567_test_result_on_fe1
2. Made Backend failover with similar steps
   as https://chefio.atlassian.net/secure/attachment/35561/35561_make+backend+failover
3. Again Ran chef-server-ctl test on fe1 and fe2. Got same result as step 1.

Note: while doing chef-backend cluster setup from /dev I required to do this changes https://gist.github.com/NAshwini/cb8ce51b6de4c8e050c149c86ad0f6bf

Happy to hear it's passing tests, looks good to me.

@tas50 and @PrajaktaPurohit Anything pending on this PR ? can we go ahead and merge it?

fwiw, I've manually tested a build of this branch (13.1.50+20200220124407) using the omnibus-chef-backend scenario with ipv4 and it passed all of the chef-server tests.

I've also kicked off a full integration_test pipeline here:

https://buildkite.com/chef/chef-chef-server-master-integration-test/builds/19

Note that ipv6 will continue to fail due to issues unrelated to this PR.

[PrajaktaPurohit]

This had been tested with chef-backend, including the chef-backend demotion scenario. https://buildkite.com/chef/chef-chef-server-master-integration-test/builds/24#_ (The builds show as failed because of some other changes not getting the expected exit code. But the tests are actually successful for chef-backend)

Thanks for digging through all the issues here!
