Allow optional, configurable exclusion of tests from cypress open dashboard.

Current behavior:

I like clicking the "Run all specs" button to quickly run integration tests locally. I have a lot of visual regression tests which always fail in cypress open because of the following issues:

• Screenshots taken during 'cypress run' do not respect the viewport size set #2102
• "fullPage" Screenshot inconsistent / wrong stitching #2175
• Full page screenshots with scale: true are not stitched together as expected, contains black borders / spacings #2348
• Taking screenshots during cypress open versus cypress run result in different screenshot sizes #3324

With the unfortunate differences in behavior between the two environments, I never run "Run all specs" in cypress open because many of the tests will fail, I never want them to run in the first place, and they take a long time to run.

Desired behavior:

Allow developers to optionally configure which tests should be excluded from running in cypress open dashboard.

@kylemh This plugin might help a little bit: cypress-skip-and-only-ui

@kylemh ...or this one: cypress-select-tests

Looks like those plugins do what I need. Thanks!
