health check playbooks: relocate and expand
We are moving toward having adhoc post-install checks and so the "preflight" designation needs to be widened. Updated location to playbooks/byo/openshift-checks, added health check playbook, and updated README. Also included the certificate_expiry playbooks. Left behind symlinks and wrappers for existing checks. To conform with the direction of the rest of the repo, the openshift-checks playbooks are split into two directories, one under playbooks/common with the actual invocation and one under playbooks/byo for entrypoints that are just wrappers for the ones in common. Because the certificate_expiry playbooks are intended not just to be functional but to be examples that users modify, I did not split them similarly. That could happen later after discussion but for now I just left them whole under byo/openshift-checks/certificate_expiry.

+# OpenShift health checks
+
+This directory contains Ansible playbooks for detecting potential problems prior
+to an install, as well as health checks to run on existing OpenShift clusters.
+
+Ansible's default operation mode is to fail fast, on the first error. However,
+when performing checks, it is useful to gather as much information about
+problems as possible in a single run.
+
+Thus, the playbooks run a battery of checks against the inventory hosts and have
+Ansible gather intermediate errors, giving a more complete diagnostic of the
+state of each host. If any check failed, the playbook run will be marked as
+failed.
+
+To facilitate understanding the problems that were encountered, a custom
+callback plugin summarizes execution errors at the end of a playbook run.
+
+# Available playbooks
+
+1. Pre-install playbook ([pre-install.yml](pre-install.yml)) - verifies system
+ requirements and look for common problems that can prevent a successful
+ installation of a production cluster.
+
+2. Diagnostic playbook ([health.yml](health.yml)) - check an existing cluster
+ for known signs of problems.
+
+3. Certificate expiry playbooks ([certificate_expiry](certificate_expiry)) -
+ check that certificates in use are valid and not expiring soon.
+
+## Running
+
+With a [recent installation of Ansible](../../../README.md#setup), run the playbook
+against your inventory file. Here is the step-by-step:
+
+1. If you haven't done it yet, clone this repository:
+
+ ```console
+ $ git clone https://github.com/openshift/openshift-ansible
+ $ cd openshift-ansible
+ ```
+
+2. Run the appropriate playbook:
+
+ ```console
+ $ ansible-playbook -i <inventory file> playbooks/byo/openshift-checks/pre-install.yml
+ ```
+
+ or
+
+ ```console
+ $ ansible-playbook -i <inventory file> playbooks/byo/openshift-checks/health.yml
+ ```
+
+ or
+
+ ```console
+ $ ansible-playbook -i <inventory file> playbooks/byo/openshift-checks/certificate_expiry/default.yaml -v
+ ```
+
+## Running via Docker image
+
+This repository is built into a Docker image including Ansible so that it can
+be run anywhere Docker is available. Instructions for doing so may be found
+[in the README](../../README_CONTAINER_IMAGE.md).

-Ansible's default operation mode is to fail fast, on the first error. However,
-when performing checks, it is useful to gather as much information about

-
-With an installation of Ansible 2.2 or greater, run the playbook directly
-against your inventory file. Here is the step-by-step:

-1. If you haven't done it yet, clone this repository:
-
- ```console
- $ git clone https://github.com/openshift/openshift-ansible
- $ cd openshift-ansible
- ```
-
-2. Run the playbook:
-
- ```console
- $ ansible-playbook -i <inventory file> playbooks/byo/openshift-preflight/check.yml
- ```
