Make Clowder properties source more tolerant

[awood]

Jira issue: SWATCH-4580

Description

If a property value is prefixed with "clowder.", the ClowderJsonPropertySource is engaged. It examines the cdappconfig.json file and extracts the necessary information for an endpoint. However, if the endpoint is not present in the ClowdApp, there is no corresponding entry in the cdappconfig.json file. The previous behavior was for ClowderJsonPropertySource to throw an exception in this case.

When we are doing component testing, we intentionally remove endpoints that would normally be present in order to reduce the deployment footprint. This commit makes ClowderJsonPropertySource tolerate that case and print a warning instead of throwing an exception.

This commit also creates a template parameter for the swatch-contracts hostname and sets an appropriate default for it. In a component testing deployment, we'll want to set that hostname to point to the wiremock container. This commit also sets the swatch-contracts certificate truststore to default to the empty string. This value will cause the TlsProperties class to avoid loading a truststore (since there is no truststore in this deployment scenario).

Finally, this commit also sets environment variables for several template parameters. The parameters existed previously but were never dereferenced anywhere which made them unusable.

Testing

Setup

1. bin/build-images.sh rhsm-subscriptions

Steps

1. Do a limited deployment of swatch-tally. Note that the dependency on swatch-contracts is being removed.

   VER=$(git rev-parse --short=7 HEAD) ;
   REPO=$(podman login quay.io --get-login) ; \
   bonfire deploy rhsm \
   --source=appsre \
   --ref-env insights-production \
   --optional-deps-method none \
   --frontends false \
   --no-remove-resources app:rhsm \
   -i quay.io/$REPO/rhsm-subscriptions=$VER \
   -p swatch-tally/IMAGE=quay.io/$REPO/rhsm-subscriptions \
   -p swatch-tally/RHSM_CONTRACTS_URL=http://wiremock-service:8000 \
   --remove-dependencies swatch-tally/swatch-contracts \
   --component wiremock \
   --component rhsm \
   --component artemis \
   --component swatch-kafka-bridge \
   --component swatch-tally
   

Verification

1. oc logs -f $(oc get pods | grep swatch-tally-service | cut -f1 -d' ') to monitor for a successful deployment of swatch-tally-service.
