Document healthcheck and container build issues

Browse Source 
Because healthchecks are provided via packaging in the build process,
you cannot update the image yaml files and make healthcheck changes in a
single commit. They need a level of coordination to not break things.

# Notes about changing healthchecks
Because healthchecks are provided via a package when building containers,
you cannot rename or remove a health check in combination with a change to a,
file in tripleo-common/container-images/. Changes need to be backwards and
forwards compatible when updating healthchecks. You may also need to land
a new healthcheck first and update the container build process in a subsequent
change that lands later.
