This is the first step in converting out static strings into well-defined
error types. This shows just a few examples of it to get a feel for how things
will look. Once we agree on the basic outline we can then work on converting
the rest of the code over.

If a logdriver doesn't register a callback function to validate log
options, it won't be usable. Fix the journald driver by adding a dummy
validator.
Teach the client and the daemon's "logs" logic that the server can also
supply "logs" data via the "journald" driver. Update documentation and
tests that depend on error messages.
Add support for reading log data from the systemd journal to the
journald log driver. The internal logic uses a goroutine to scan the
journal for matching entries after any specified cutoff time, formats
the messages from those entries as JSONLog messages, and stuffs the
results down a pipe whose reading end we hand back to the caller.
If we are missing any of the 'linux', 'cgo', or 'journald' build tags,
however, we don't implement a reader, so the 'logs' endpoint will still
return an error.
Make the necessary changes to the build setup to ensure that support for
reading container logs from the systemd journal is built.
Rename the Jmap member of the journald logdriver's struct to "vars" to
make it non-public, and to make it easier to tell that it's just there
to hold additional variable values that we want journald to record along
with log data that we're sending to it.
In the client, don't assume that we know which logdrivers the server
implements, and remove the check that looks at the server. It's
redundant because the server already knows, and the check also makes
using older clients with newer servers (which may have new logdrivers in
them) unnecessarily hard.
When we try to "logs" and have to report that the container's logdriver
doesn't support reading, send the error message through the
might-be-a-multiplexer so that clients which are expecting multiplexed
data will be able to properly display the error, instead of tripping
over the data and printing a less helpful "Unrecognized input header"
error.

This defines a 'context' object that is passed to each API handler.
Right now the context just has a unique 'requestID' for each API call.
The next steps would be:
- use this 'requestID' in our logging.
- determine the best way to format the logging to include this info.
In particular for log events that generate multiple entries in the log
we can use the requestID to help correlate the log entries.
Adding the requestID to the logging will be a challenge since it could mean
changing every single logrus.XXX() call to pass in the 'context' object.
But first step is to agree on a format, which we can discus in a subsequent
PR, but my initial thoughts are to add it right after the timestamp:
current format:
INFO[0039] POST /v1.21/build?buildargs=%7B%22foo%22%3A%22xxx%22%7D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&memory=0&memswap=0&rm=1&t=&ulimits=null
proposed format:
INFO[0039-83dea1222191] POST /v1.21/build?buildargs=%7B%22foo%22%3A%22xxx%22%7D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&memory=0&memswap=0&rm=1&t=&ulimits=null

For now CLI `docker stats` will not block even if the container was
not running is because there is a 2s timeout setting when waiting for
the response.
I think why we hang there waiting for the container to run is because we
want to get the stats of container immediately when it starts running.
But it will block when use the API directly, for example
- curl
- Google Chrome plugin, Postman
- Firefox plugin, RESTClient
This patch keeps the feature that getting info immediately when container
starts running and in the meantime, it will not block when using the API
directrly.
