WIP: new branch to clean up all the crap I pulled in with a merge with development

adding updates for arguments to upload-to-harbor.sh in harbor.yaml, updated upload-to-harbor.sh with workflow for notary image signing, added local-delegation.sh script to scripts/ dir for inital key creation and snapshot rotation.

New required CI variables:

• NOTARY_URL
• NOTARY_AUTH
• NOTARY_DELEGATION_PASSPHRASE
• NOTARY_DELEGATION_KEY

Definitely need @blake.burkhart @david.freeman @gavin.scallon @ariel.shnitzer eyes on this.
