* Updates the dashboard and screenshot deploy script to exit the process immediately if the Firebase token is not set.
* Fixes that the error message of the dashboard still shows the old name of the token variable
* Renames the screenshot variables to follow the dashboard environment variables
* Explicitly specifies the project that will be uploaded in the screenshot deploy script (same as for dashboard)
* instead of using a complex RegExp that will likely break at some point in the future, we are switching to a single-line NodeJS script to resolve the version.
Currently whenever something fails in the deploy script it will likely not cause the CI to show the failure. This is because Bash by default doesn't exit the process with the proper error code.
* Currently the `0.0.0-PLACEHOLDER` is still inside of the `package.json` of the material2-builds. Similar as for every other Angular package the version placeholder should be replaced with the version of the current "build commit".
Closes#5320
* Updates the version of Sauce Connect to avoid potential flakes within the Saucelabs tunnels
* Fixes the invalid path for the `deploy-dashboard` script that runs in the deploy build stage
* build: add dashboard firebase functions
* Adds a new folder for the dashboard project that for now only contains firebase functions.
* The firebase functions will be used to securely make API calls to the Github API (e.g payload status)
* Functions will be automatically deployed as same as screenshot functions.
* Address feedback
