CHANGELOG and README fixups about ManageIQ#554, ManageIQ#555

Tiny followup to ManageIQ#556.
Sorry for noise, had these locally but forgot to push before merging.
If I start backporting, CHANGELOG.md on master branch might not always be updated
with all backports (it SHOULD, but it will require separate merges to master).
So I prefer pointing to the vulnerability issue as the "source of truth".
Also, security impact will be better discussed on the issue.

 - Bug fix: kubeconfig `insecure-skip-tls-verify` field was ignored.
   When kubeconfig did define custom CA, `Config` was returning hard-coded `VERIFY_PEER`.
 
   Now we honor it, return `VERIFY_NONE` iff kubeconfig has explicit
   `insecure-skip-tls-verify: true`, otherwise `VERIFY_PEER`.
 
+  [#555](https://github.com/ManageIQ/kubeclient/issues/555).
+
 - `Config`: fixed parsing of `certificate-authority` file containing concatenation of
   several certificates.  Previously, server's cert was checked against only first CA cert,
   resulting in possible "certificate verify failed" errors.
