Add the ability to skip canaries on skip releases

Is your feature request related to a problem? Please describe.

Talked to @hipstersmoothie about this on twitter, but I wanted to document it for good measure. Currently running auto canary in CI will always produce a canary, regardless of what labels are on a PR. For cases where we don't intend to ship a release (especially with documentation or dependency updates) it'd make sense to avoid generating canaries.

Describe the solution you'd like

Add a mechanism to skip releases to auto canary. It could be an explicit argument added to the canary command to check labels or some other mechanism.

Describe alternatives you've considered

We could choose not to solve this and instead push it to user land for them to decide how best to run or not run auto canary based off of whatever conditions they have. We do already have auto label which does help a bit.

Would using the existing labels on a PR help with this? If documentation or dep-update labels are mapped to a not generate a release, auto canary also won’t produce one.

Can also use a —force flag to force it to create a release, or maybe a way to ignore labels supplying your own semver bump.

Yep, I like that idea. It’s somewhat breaking to how it currently functions, but more in line with what I’d expect.
