[autotest] Send frontend jobs to shards.
Frontend jobs on hosts that are on the shard are disallowed
currently, because the host-scheduler on master currently
ignore jobs based on meta-host, but frontend jobs have no
meta-host. This CL have the following changes:
- Make host-scheduler ignore frontend jobs that are supposed
to be picked by shard.
- Send such frontend jobs in heartbeat.
- Allow creation of frontend jobs in rpc.
TEST=Test the follows:
- Create a job on a host on shard from AFE frontend.
Observe it runs on shards and completes on master.
- Create a job on two hosts (one host on shard, the other on master)
from AFE frontend. Make sure exception is railed with correct
message.
- Run a normal dummy suite on shard, make sure normal flow still
works. Heartbeat contains the right information.
- Run a normal dummy suite on master, make sure it works.
