Scripts fail when CONJUR_OSS_HELM_RELEASE_NAME is not set

Summary

The scripts currently require that the environment variable CONJUR_OSS_HELM_RELEASE be set. This environment variable is set in our CI test scripts, but typical users of these scripts would not be aware that this setting is required.

The symptom is that if you run the scripts without setting this environment variable, you would see:

Retrieving Conjur certificate.
./5_app_store_conjur_cert.sh: line 14: CONJUR_OSS_HELM_RELEASE_NAME: unbound variable

Summarizing this issue:

There's already an environment variable HELM_RELEASE that can be used for CI.
Required variables should have an entry in bootstrap.env, since this is our documentation to users advising what the minimal settings are to run the scripts.
Required variables should have a check in the 0_prep_check_dependencies script.

Steps to Reproduce

Steps to reproduce the behavior:

Run the scripts without setting CONJUR_OSS_HELM_RELEASE_NAME and voila.

Version/Tag number

What version of the product are you running? Any version info that you can share is helpful. For example, you might give the version from Docker logs, the Docker tag, a specific download URL, the output of the /info route, etc.

Environment setup

Can you describe the environment in which this product is running? Is it running on a VM / in a container / in a cloud? Which cloud provider? Which container orchestrator (including version)? The more info you can share about your runtime environment, the better we may be able to reproduce the issue.
