Code Issues Proposed changes
openstack-helm/doc/source/devref/getting-started/conditionals.rst
mattmceuen cf4c6d50de Clarified a couple documentation points. 
Conditionals:  since the developer flag is no longer used by the
glance chart, it's no longer a good example.  However, we want to
keep the flag around for future use if needed.  So, replaced with
a foo/bar example.

gen-oslo-openstack-helm README:  it referred to "this directory",
which doesn't make sense when the README is sourced into the
overall ops guide.  Specified the directory explicitly.

Common Conditionals

The OpenStack-Helm charts make the following conditions available across all charts, which can be set at install or upgrade time with Helm below.

Developer Mode

helm install local/chart --set development.enabled=true

The development mode flag should be used by any charts that should behave differently on a developer's laptop than in a production-like deployment, or have resources that would be difficult to spin up in a small environment.

A chart could for instance define the following development: override to set foo to bar in a dev environment, which would be triggered by setting the enabled flag to true.

development:
  enabled: false
  foo: bar

Resources

helm install local/chart --set resources.enabled=true

Resource limits/requirements can be turned on and off. By default, they are off. Setting this enabled to true will deploy Kubernetes resources with resource requirements and limits.
