Description of Change

This PR changes the Jenkins pipeline to allow setting the docker environment via the NODE_LABEL parameter. This will allow us to run the lower environments in the SmartThings pre-prod VPC and call internal cloud endpoints.

Changes:

• Remove the environment matrix and specify the environment be the NODE_LABEL parameter.
• Add a DRY_RUN parameter that allows running the pipeline without doing a bulk upload.
• Add the X-ST-CORRELATION header to cloud api requests to improve traceabillity in cloud logs.

Summary of Completed Tests

We have used the new pipeline to do dry run deployments in all lower environments and confirmed that they are able to make api requests using internal endpoints.
