Move Jenkins nightly build for 1.1 into prod jenkins stack

[mch2]

This task involves moving this job into the production jenkins stack.

This job builds a SNAPSHOT version of OpenSearch artifacts and publishes to our snapshot maven repository.
In parallel it builds a release version for x64 and arm64 and publishes to an S3 bucket. For this task, this should be the public bucket that powers artifacts.opensearch.org.

As part of this job the following plugins will need to be installed and available:
aws-steps - For assuming necessary roles to perform S3 uploads
pipeline-utility-steps For parsing YAML

See #179 for some remaining tasks on snapshot builds.
