Consider adding a means to turn on default lints with an analysis option.

[pq]

The analyzer supports a default set of lints with the --lints flag. We should consider a means to flip this bit with .analysis_options as well. (See flutter/flutter#5573 for discussion.)

FWIW, I think support for lint groups is the better way to do this. We could have a single solution that would satisfy all of the known use cases instead of multiple solutions that overlap and conflict. The --lint option could be extended to take a group, and if none is given could default to the "default" group.
