AU: OmahaRequestAction: allow to be skipped.
This CL changes OmahaRequestAction to take a request to skip its
action when it's run. This will be useful in a future CL, where we'll
want to schedule an OmahaRequestAction to run, but then in some cases
prevent it from actually doing so.
This also changes MockHttpFetcher to be able, if properly configured,
to fail it it's used. This is used in the test to make sure that a
skipped OmahaRequestAction does no HTTP traffic.
