Parity with Google style guide

[smaye81]

Make the current google lint group have full parity with the google style guide.

For example, enforce plural names for repeated fields.

Note that this will not be full parity as support for plural names on repeated fields will not be added.

Going to close this in favor of focusing more on the uber rule sets.
