Don't include boto tests as part of smoke tests

Tests with the smoke attribute are used all over when we want to run a
subset of tempest. The smoke job is supposed to be a subset that gives
us the most bang for the buck in functional test validation. The ec2 api
falls outside of that being a third party api its always going to be
extra.
