Brian Goff 054abff3b6 Implement optional ring buffer for container logs 
This allows the user to set a logging mode to "blocking" (default), or
"non-blocking", which uses the ring buffer as a proxy to the real log
driver.

This allows a container to never be blocked on stdio at the cost of
dropping log messages.

Introduces 2 new log-opts that works for all drivers, `log-mode` and
`log-size`. `log-mode` takes a  value of "blocking", or "non-blocking"
I chose not to implement this as a bool since it is difficult to
determine if the mode was set to false vs just not set... especially
difficult when merging the default daemon config with the container config.
`log-size` takes a size string, e.g. `2MB`, which sets the max size
of the ring buffer. When the max size is reached, it will start
dropping log messages.

```
