Upgrade Notices

New config values were added to the BBCTL config structure under the top level gitlab field. Token can be an empty string for now since we are not pulling from any private repositories for the update check functionality. ex:

...
"bbctl-log-format": "text"
"gitlab":
    "base-url": "https://repo1.dso.mil"
    "access-token": ""
