Allow users to provide additional projected volumes to be mounted into
the various deployments, statefulsets, and jobs that the cloudkitty chart has
in the /etc/cloudkitty/cloudkitty.conf.d/ path. This allows for users to provide
service account or database secrets via different operators as well as
provide ways to use the chart to define common deployments while being
able to have site specific overrides.
