Channels are a concept similar to job types. Callers must specify a channel
name when queueing a new job. A list of channels is also specified when
dequeueing a job. The dequeued job's channel will always be from one of the
specified channel. Of course, the job types are also respected. The dequeued
job will also always be from one of the specified type.
Currently, all calls to jobqueue were changed so all queue operations use
an empty channel name and all dequeue operations use a list containing
an empty channel.
Thus, this is a non-functional change.

Replace Job() and JobStatus() with typesafe versions, and introduce JobType()
for the rare instances where we don't know the type up front.
Additionally, catch a few more error cases:
- if OSBuildResult is nil, then we failed to invoke osbuild
- make sure the same JobResult handling is done for osbuild-koji, as for osbuild
Since the workers will use structured error messages
going forward, it is necessary to maintain backwards
compatability for there errors in composer. Tests have
been added to the various apis to ensure that each api
checks for both kinds of errors, old and new.
