Improve debugging of cam-pipeline on Kubernetes

[gaurav]

This PR does this by:

• Upgrading to cam-pipeline-tools:dev to pull in changes from https://github.com/ExposuresProvider/cam-pipeline-tools/pull/4 and https://github.com/ExposuresProvider/cam-pipeline-tools/pull/5
• Adding a Kubernetes Pod description that is identical to build-cam-database.yaml and that connects to the same PVC, but creates a single pod rather than a CronJob, and does not automatically start the build process. This can be used to fix errors on the PVC or to try something new before incorporating it into the build-cam-database CronJob.

This should be merged after #78
