This allows the caller to receive multiple times without blocking after
the first call.
This can be useful in cases like this:
```go
ch, _ := task.Wait(ctx)
defer func() { <-ch } // don't return until task is done
task.Start(ctx)
if err := doSomething(task); err != nil {
return err
}
status := <- ch
// do stuff with status
```
Since this channel is created in the `Wait()` calls and never accessible
outside, this should be safe.

Content commit is updated to take in a context, allowing
content to be committed within the same context the writer
was in. This is useful when commit may be able to use more
context to complete the action rather than creating its own.
An example of this being useful is for the metadata implementation
of content, having a context allows tests to fully create
content in one database transaction by making use of the context.

Fixes#1374
This adds a `LoadProcess` api to load existing exec'd processes from a
task. It allows reattaching of IO and waiting on the process.

Instead of requiring callers to read the struct fields to check for an
error, provide the exit results via a function instead which is more
natural.
