Proposal: Support process for managing environments

[jennifer-shehane]

Current behavior:

Users want to run their test suite across environments (dev, staging, prod) and easily see the environment the tests were run in (from the Test Runner and the Dashboard)

Related gitter convo: https://gitter.im/cypress-io/cypress?at=5b35971d6ceffe4eba3c6d82

Desired behavior:

Have an official way to specify the environment Cypress will be run in so that this data can be shown while reviewing tests run later.

Versions

Cy: 3.0.2

We've discussed having something like a --label flag to pass through on cypress run and whatever was written here would be displayed in the list of runs. So you could do:

cypress run --label=production
cypress run --label=develop

Need a char limit on what's allowed here, because this label would then be displayed in the runs list.
